the same old thing

here’s yet another version of this thing
(which, like all its predecessors, is unreadable
in the version posted here; don’t get me started):
four “representations” of the 24-element group
called variously “the binary tetrahedral group”,
“the hurwitz units”, SL_2(F_3), and A-four-hat
(among other things).

new here are the yin-yangs on the g-coset points
of the generators-and-relators version at upper left.
and nothing else. still, it’s an entire course
in group theory summarized on one page and it cost me
quite a bit of effort figuring out what to put where.
maybe some of the bits-into-graphics pages of my book
were as much trouble as this but i doubt it. anyhow,
i’ve long since given up on ever again getting anybody
to read *that* damn thing so i’m stuck with this until
i find a better obsession. read the ten page news.
