Question re: Omaha showdowns

Do we have a code repository up yet? Is there a more elegant way of
handling Omaha showdowns than examining SIXTY potential high hands and some
number of lows approaching that?

Play exactly two from four (six combinations), plus exactly three from five
(ten combinations), and you have to look at sixty hands, just to determine
the highest hand YOU have. That's 600 "high hand" calculations at a
"family showdown".

I can't think of a better way out of this, other than to look at all sixty
possibilities, and take the best (or for low, worst) ranking ones as the
"reading" of the hands.

Anyone have anything more elegant?
