Wooooooooooooooooooooooooooooot!

I just calculated the cohomology of the dihedral group on eight elements (i.e. the symmetry group of the square). Go me!

Yay! There's a great film called "The Symmetries of a Cube" that I've seen a number of time ... Any relation? :-)

[michiexile]

No idea. What's the film about?

[rkaj.livejournal.com]

It's an old (probably 1930 - 1950 sometime) instruction film showing all symetry axises/planes in a cube (and there is lots of them), using a physical model of a cube, and a mirror placed in the symetry plane currently beeing shown. It is shown (or at least, it used to be shown, as part of the "n0llning" at EE, KTH.

I guess what you've done was more theoretical? :-)

[michiexile]

A bit. And more importantly, I'm not certain whether the symmetries of the cube form a dihedral group....

S₄, IIRC. *googles* It seems to be S₄ x C₂.

There's a PhD student at Glasgow who does a lot of this sort of stuff - I could put you in touch if you like...

[michiexile]

Coooool; I wouldn't mind.

Um... go, you!

(Actually, going by how excited you are about this, GO, YOU! even.)

This is still in the phase of "Geee, I gotta figure out what the heck I'm supposed to be doing these next few years" - and it was done with more handholding than I would have wanted; but it is a tangible step forward!
