%N a(n) is the number of preference profiles in the stable marriage problem with n men and n women that generate the maximum possible number of stable matchings.
%C From _Dan Eilers_, Dec 23 2023: (Start)
%C A357271 provides the best known lower bounds for the maximum number of stable matchings of order n.
%C A357269 provides exact results. (End)

%F a(n) = A368433(n) * A010790(n-1). - _Dan Eilers_, Dec 24 2023
%e For n=2, there are 16 possible preference profiles: 14 of them generate one stable matching and 2 of them generate two stable matchings. Thus, a(2) = 2.
