Binomial coefficients are found in, for 10 points, what French mathematician and philosopher's namesake "triangle"?
This mathematician names the theorem that for a hexagon inscribed in a conic, opposite sides' extensions' intersections are collinear. He corresponded with Pierre de Fermat [fair-mah] to develop probability theory, although that work is unrelated to a theological (*) wager named for him. He also lends his name to a structure whose rows add up to powers of two. Binomial coefficients are found in, for 10 points, what French mathematician and philosopher's namesake "triangle"?
