Thanks!

you're absolutely right -- I didn't have a calculator with choose[] handy, and I was accidentaly computing the permutation function ((50! / (50-3)!) = 50 * 49 * 48) rather than the choose function ((50! / ((50-3)! * 3!)) = 50 * 49 * 48 / 6) which is why I was counting 117600 flops instead of the real number, 117600 / 6 = 19600!

thanks, irchans! apologies, Cyrus!
