hi @ericgjackson I want to know the relationship between "the number of the boards" and "the number of the buckets". I know there are 169 buckets on the pre-flop,1755 buckets on the flop after removing isomorphisms. But the number of the boards makes me confused . look forward to your reply :) st 0：1 boards 169 buckets st 1 : 1755 boards 1286792 buckets st 2 : 63193 boards 1927 buckets st 3: 2554656 boards 1950 buckets
