the camera built into legion (= my mac-book)

broke a few months back (or the software

decided to mess with me… what amounts

to the same thing). so i haven’t been posting

photos. but my office at Big State U has a mac

and it turns out i still remember how (to make ’em

and to post ’em in this rather clunky way).

what we have here… but what *belongs*

in MEZB (i *told* you it was clunky)… is

a picture of the theorem $P_2({\Bbb F}_5) \equiv P_2({\Bbb F}_5)^*$

(“the two-dimensional projective space constructed

on the field with five elements is isomorphic to its own

dual space”).

i put it in a zine recently (along with diagrams for

$P_2({\Bbb F}_2)$ and $P_2({\Bbb F}_7)$;

${\Bbb F}_3$ is left as an exercise).

i didn’t put the extra carriage-returns in of course;
cutting-and-pasting isn’t what it’s cracked up to be.
