Probably Art # 187: Polygon

133-sided polygon with vertices chosen from 7 distance(s) from the origin.

$$ s = .00037761, \; $$ $$ | \lbrace \theta \rbrace | = 133, $$ $$ | \lbrace r \rbrace | = 7,$$ $$ r_0 = 0.2500,$$ $$ R = 1.00, $$ $$r \sim \beta(0.640, 0.972), $$ $$\theta \sim \beta(1.000, 1.000). $$
