Gordon Swain: I'm here (slipping into back of room)

Dennis Keeler: hi
Julianne Rainbolt: hi tom and dennis
Tom Hoffman: hi
Julianne Rainbolt: QT:rtsp://165.134.240.35/GAP060711am1.sdp
Dennis Keeler: thanx
Julianne Rainbolt: VNC: 165.134.13.231
Julianne Rainbolt: russell is returning to Section 3
10:10 AM
Benjamin Collins: OK, here's a pedagogical question. Do you really think that these two exercises provide better insight (or even different insight) than just looking at plane figures and trying to figure out what their symmetries are?
10:20 AM
Jen Roche: quickly, is that orderFrequency function "better" at the bottom of page 4?
Russell Blyth: it should be the same?
Jen Roche: sure, the same, but any reason for another, or just mathematical joy?
Russell Blyth: video up on am2
Daniel Shown: rtsp://165.134.240.35/GAP060711am2.sdp
Julianne Rainbolt: we just repeated it because when we were putting together the material we were worried some one might miss the first version
Jen Roche: okay, thanks!
Julianne Rainbolt: if they were having trouble with QT and vnc on the first day
Gordon Williams: Why use permutation representations all the time?
Jen Roche: i have that question too
10:25 AM
Russell Blyth: did you hear my answer/
Jen Roche: yes here
Gordon Williams: yup
Julianne Rainbolt: We've switched This is Russell now
10:30 AM
Gordon Williams: Can you not have both LogTo and InputLogTo running at the same time?
Julianne Rainbolt: no
Anne Collins: does the presence of InputLogTo(); at the end of a function file hurt anything?
Anne Collins: (since i'm apt to forget to delete it)
Anne Collins: okay, as long as it'll reming me...
10:35 AM
Chirashree Bhattacharya: separate file for each function?
Gordon Williams: not necessarily
Anne Collins: is there a "dot-something" at the end of a gap function file in windows?
Brian Walter: only if you put it there
Julianne Rainbolt: right
Anne Collins: 
Brian Walter: adding .txt to the end will make it so windows knows what application to use to open it
Jen Roche: so you could put all of your preliminary materials into just one file (functions/ definitions) and then read them all in at once?
Russell Blyth: yes
Jen Roche: wow
Anne Collins: windows doesn't puke without an extension?
Jen Roche: not always!
Brian Walter: no - mine is doing ok
10:40 AM
Tom Hoffman: adding a .gap extension is a good reminder for the user
Anne Collins: 'kay (i'm in linux now)
10:45 AM
Tom Hoffman: Do you expect students to finish these projects in class, or do you just get them started?
Dennis Keeler: so you teach this in a computer lab?
Dennis Keeler: is every day in the lab, or do you have a pattern?
Dennis Keeler: pattern of classroom and lab...
Julianne Rainbolt: every day, usually
Bill Abrams: If your students have laptops and half of them can remember to bring them.....
Julianne Rainbolt: It's really a computer classroom, rather than a lab
Julianne Rainbolt: We WANT students to work in groups
Tom Hoffman: do they finish the projects in groups?
Julianne Rainbolt: Yes
10:50 AM
Julianne Rainbolt: They are still responsible for written homework individually
Julianne Rainbolt: Video up ...am3
Daniel Shown: rtsp://165.134.240.35/GAP060711am3.sdp
Julianne Rainbolt: Everyone OK?
10:55 AM
Benjamin Collins: Is there someway to access the elements of the set "groups40"? Can I, say, ask how many elements of order 10 there are in each group?
Dennis Keeler: yes. I played with this. It's a list
Dennis Keeler: use groups40[1], groups40[2] ...
Dennis Keeler: but hard to tell which is which
Benjamin Collins: No, I had the list. I'm wondering how to work with it.
Benjamin Collins: Thanks, Dennis.
Jen Roche: so what about that "groups40.1" notation?
Dennis Keeler: didn't work
Julianne Rainbolt: that's for records
Julianne Rainbolt: this is a list
Gordon Williams: Filtered(groups40[1],x -> Order(x)=10);
Dennis Keeler: IsAbelian(groups40[n]) is useful for at least picking out the abelian examples
Gordon Williams: This will give you the list of elements of order 10 in the first group in our list
Julianne Rainbolt: And now you should be able to compund that with a List() command
Brian Walter: and List(groups40, x -> IsAbelian(x)); will tell you all of them at once
Dennis Keeler: thanks. Still learning how to do loops
11:00 AM
Dennis Keeler: I likehttp://www.math.usf.edu/~eclark/algctlg/small_groups.html for groups of order <= 30
Russell Blyth: z3 + z3 + z3, sl(3,z3)
Russell Blyth: same orderfrequency
Russell Blyth: not iso
Dennis Keeler: there are non-iso groups of order 16 with same orderFrequency. Order 27 is the next source of examples.
Gordon Williams: The following will give you the list of all elements of order 10 for each of the groups:
Gordon Williams: List(groups40,x->Filtered(x,y->Order(y)=10));
11:05 AM
Julianne Rainbolt: stop video QT
Russell Blyth: to ...am4
Daniel Shown: rtsp://165.134.240.35/GAP060711am4.sdp
Anne Collins: List experts: so i type the above and GAP whines that 'x' must have a value... what gives?
Russell Blyth: up
Gordon Williams: you can also follow that with List(last,x->Size(x)); to get the numbers of those elements
Russell Blyth: you need to define groups40 first
Russell Blyth: thanks gordon
Anne Collins: i did... ?
Gordon Williams: I'm not sure, can you copy and past the exact text you typed into the chat window?
Gordon Williams: I can try and debug
Russell Blyth: I did
Gordon Williams: yeah, I'm trying to solve Anne's problem.
11:10 AM
Gordon Williams: yup, 14 groups
Anne Collins: i've got it
Gordon Williams: you would have had an empty list somewhere in the middle wouldn't you?
Anne Collins: my linux AIM is translating > as > which i caught, but didn't get the extra ; out of there.
Gordon Williams: yeah, turn off emoticons
Gordon Williams: if you can
Anne Collins: not sure how
Anne Collins: (to turn off emoticons in this version...)
Gordon Williams: sadly I don't recall how to do it in iChat, not sure what procedure would be in AIM
Anne Collins: this AIM is really bare-bones, no "options" box, so it's prolly a command-line option. oh, well...
11:15 AM
Tom Hoffman: I just looked through my options (I am also using aim in Linux) I didn't see it anywhere
Gordon Williams: I'm confused by the output notation
Gordon Williams: (1,2)^G means what?
Julianne Rainbolt: all conjugates of (1,2) in the group G
Gordon Williams: Ahhh, that's oddly consistent
Gordon Williams: I'm used to taking conjugates of groups as G^element
Gordon Williams: thanks
11:20 AM
Tom Hoffman: This would be a good place to use List
Gordon Williams: Size(x)
11:25 AM
Gordon Swain: I checked them on my PC and on my Mac and they worked.
Tom Hoffman: they worked on my pc also
Dennis Keeler: just curious: what are Linux users using for QT?
Anne Collins: l'm running QT in windows in a virtual machine (vmware)
Dennis Keeler: cool
Tom Hoffman: on Suse, I couldn't get anything to work and have a pc laptop here for the QT
