Re: number of omaha starting hands, ignoring suits
[ QUOTE ]
PokerTracker Omaha has a comical starting hand view, which shows every hand you've been dealt like so:
AAAA
AAAK
AAAT
...
2222
so... how many starting hands are there? I'm embarassed to admit I've screwed up the math twice so far.

no pair: C(13,4) = 13*12*11*10/(4*3*2*1) = 715
1 pair: 13*C(12,2) = 13*12*11/(2*1) = 858
2 pair: C(13,2) = 13*12/(2*1) = 78
set: 13*12 = 156
quads: 13
