Gordon Swain: howdie
Chirashree Bhattacharya: Hi everyone
Julianne Rainbolt: QT address:
Shaochen Yang: Hi, I have AIM, QT, and VNC.
Russell Blyth: Great, Shaochen
Julianne Rainbolt: rtsp://165.134.240.35/GAP060710pm1.sdp
Julianne Rainbolt: VNC: 165.134.12.231
Russell Blyth: Anne are you there?
Russell Blyth: Is everyone OK
Russell Blyth: ?
Gordon Williams: I'm good
Gordon Williams: qt is frozen tho
Brian Walter: my quicktime went out too
Russell Blyth: Anyone NOT OK?
Dennis Keeler: my QT froze too
Jen Roche: QT isn't good for me
Julianne Rainbolt: yes it went out here to
Russell Blyth: Hang on
Dennis Keeler: trying to restrart, no luck
Chirashree Bhattacharya: QT froze
Julianne Rainbolt: stand by
2:30 PM
Edward Moy: the QT went down
Benjamin Collins: Havign trouble with QT. Don't start yet.
Bill Abrams: Currently QT is asking me to put a disk in the drive. I do not know why
Russell Blyth: Video is up again
Julianne Rainbolt: yes QT was out - try now
Tom Hoffman: qt is back for me
Jen Roche: okay here
Russell Blyth: Anyone not OK?
Edward Moy: QT is working
Russell Blyth: Sorry about that
Gordon Williams: still broken here
Anne Collins: mine's working!
Chirashree Bhattacharya: i'm good
Shaochen Yang: QT is working for me.
Gordon Williams: better now
Brian Walter: ok, working
Benjamin Collins: Still not OK.
Julianne Rainbolt: we'll start - let us know if you have troubles
Gordon Swain: I'm good on QT
Russell Blyth: rtsp://165.134.240.35/GAP060710pm1.sdp
Bill Abrams: I still cannot get around the No Disk Problem
Julianne Rainbolt: ben get out of QT and start it again
Russell Blyth: note ..pm1
Russell Blyth: Bill, quit QT and reopen. If that has not worked, I'd reboot
Benjamin Collins: Say something, Russell.
Benjamin Collins: OK, I'm set.
Julianne Rainbolt: anyone else with problems?
Gordon Swain: I have sound, video problems, but not a big deal.
2:35 PM
Tom Hoffman: can you email Asst.doc to the listserv
Julianne Rainbolt: we will do that today Tom
Bill Abrams: I am working now. Did I miss anything
Julianne Rainbolt: you missed the assignment to come up with a list of things you might want to work on in a group with someone from the workshop this week.
Bill Abrams: Thanks,
Julianne Rainbolt: we will send out an email describing this assignment in detail this afternoon
2:40 PM
Brian Walter: it may be useful (and should be simple) to format the AIM transcript to indicate who said what, and when
Julianne Rainbolt: yes brain, that is included
Julianne Rainbolt: thanks brian -we'll fix that
Brian Walter: super

Gordon Swain: Thanks, that's clear.
Brian Walter: it seems like it should be simple to include an option in GAP that lets you choose which order multiplication happens in; perhaps we can lean on the authors to include it in the next version
2:45 PM
Dennis Keeler: thanks. Much easier than my way.
Brian Walter: yes - given the current version of the software, it would be complicated for a user to adjust.
2:50 PM
Brian Walter: but for the authors of the software it would just be a cosmetic change and therefore quite easy to make
Julianne Rainbolt: You'd think. They might not agree! I can take this up with a research colleague who has GAP developer status
Brian Walter: yeah, if they agreed they'd probably have done it already...
Benjamin Collins: I really like problem 1.13, but a proof of my conjecture doesn't seem to be straightforward. Am I being dense, or is it really kind of tough?
Chirashree Bhattacharya: x=2,n?
Jen Roche: gcd(x-1,n)=1
Jen Roche: generates all of S_n
Dennis Keeler: Yes, same conjecture as jlr7h, but don't have proof
2:55 PM
Jen Roche: something about gcd's again
Gordon Swain: n, x-1, and y-x?
Russell Blyth: yes
Gordon Swain: I get bonus points?
Russell Blyth: which is equivalent to gcd(n,x-1, y-1)
Russell Blyth: video is going down
Julianne Rainbolt: video will be ...pm2.sdp
Julianne Rainbolt: stand by
3:00 PM
Julianne Rainbolt: video is up
Brian Walter: up, up, and away!
Russell Blyth: rtsp://165.134.240.35/GAP060710pm2.sdp
Julianne Rainbolt: anyone not OK?
Gordon Swain: Looks good
Jen Roche: here too
Benjamin Collins: Can I access LargestMovedPoint for my group?
Tom Hoffman: yes
Benjamin Collins: OK, got it.
3:05 PM
Dennis Keeler: an abelian grape
Brian Walter: ZORN'S LEMON
Brian Walter: 
3:10 PM
Tom Hoffman: Is it important that you are defining your new group as a subgroup of S8?
Tom Hoffman: My question is more about why do you use the Subgroup command in GAP, why not just define the group generated by the 2 permutations.
3:15 PM
Gordon Williams: it occurs to me we don't have a transcript of the answers to questions posed here
Julianne Rainbolt: quicktime audio is included in the transcripts of each session
Gordon Williams: thanks
3:25 PM
Chirashree Bhattacharya: any way to compute all isomorphisms?
Brian Walter: interesting that it finds the third isomorphism (between K6 and K4) very quickly once it knows the other two
Gordon Williams: hunh? third isomorphism? I only see 2 on the display
Brian Walter: sorry, i had it find IsomorphismGroups(K6,K4) after the other two
Gordon Williams: wouldn't it just be faster because they are in a smaller permutation size context?
Julianne Rainbolt: video will shut down and return with pm3
Benjamin Collins: Actually, Gallian has a fair number of problems "Find the number of distinct isomorphisms between...."
Daniel Shown: rtsp://165.134.240.35/GAP060710pm3.sdp
Julianne Rainbolt: there is an IsIsomorphism command that tests whether a given map is an isomorphism
Russell Blyth: Video is up
Russell Blyth: Anyone not OK?
Julianne Rainbolt: this could be useful with some of these Gallian problems you refer to Ben
3:30 PM
Julianne Rainbolt: we will discuss this command after we introduce how to create homorphisms
Tom Hoffman: You could use the command AutomorphismGroup once you have one isomorphism
Julianne Rainbolt: yes
Julianne Rainbolt: this command lists all the automorphism a group onto itself
3:35 PM

Benjamin Collins: I'm sorry...where are we in the handouts?
Benjamin Collins: Thanks.
Julianne Rainbolt: page 1 of section 3, 3.1
Tom Hoffman: Will we get into xgap and the subgroup diagrams given there?
Julianne Rainbolt: we are hoping to show some xgap on friday
3:45 PM
Jen Roche: a^gcd of the 2 #'s
3:50 PM
Gordon Swain: gen'd by lcm of i,j
Julianne Rainbolt: yes a^(lcm(i,j))
3:55 PM
Julianne Rainbolt: any one not able to read in orderFrequency?
Benjamin Collins: worked for me.
Jen Roche: got it
Gordon Swain: I think I have it. I just moved the file in to bin
Brian Walter: fine for me
Shaochen Yang: fine for me.
Chirashree Bhattacharya: needed .txt
Brian Walter: is there a command in GAP to tell you what files are in the current directory?
4:00 PM
Tom Hoffman: You can in Linux
Julianne Rainbolt: within GAP? how do you do that?
Brian Walter: sure - i can do it, but i prefer to be as lazy as possible.
Tom Hoffman: yes
Tom Hoffman: I will send an email, I have to look it up.
Julianne Rainbolt: thanks tom
Brian Walter: thanks to the organizers for a great first day!
