%N a(n) is the number of preference profiles in the stable marriage problem with 4 men and 4 women that generate n possible stable matchings.

%C A185141(n) is the total number of preference profiles for n men and n women.

%C A185141(4) = 110075314176 is the sum of the terms of this sequence.

%C For 2 men and 2 women, the total number of preference profiles is 16, where 14 profiles have 1 stable matching, and 2 profiles have 2 stable matchings.

%C For 3 men and 3 women, the total number of preference profiles is 46656, where the number of possible stable matchings ranges from 1 to 3. The distribution is provided by sequence A344666(n).
