[math-fun] mystery constant .32810656687498

is the largest nome, q, for which the closed curve x=theta_2(t,q), y=theta_1(t,q) is convex. Plouffe's inverter gives me 3281065668749782 = (m405) 1/NineConst^(1/2) Trying to parse "NineConst", I tried both squaring and reciprocating, and got "Not found"! And Simon seems to be away fom his email. ? --rwg
