### more pi day high-jinx: the line at infinity

here in the middle are the seven colors
in “mister big $\pi$-oh” (from ohio) order:
MRBGPYO
(mud, red, blue, green, purple,
yellow, orange). i’ve drawn the “line”
(which appears as a triangle) formed by
“marking” the purple vertex and performing
the “two steps forward and one step back”
procedure: one easily verifies that
{G, O, P} is a line as described in
the previous post (“the secondaries”).

all to do with “duality in $P^2({\Bbb F}_2)$“.
had we but world enough. and time. especially time.
