%N a(n) is the number of (strict) chains of subspaces with ends 0 and (F_5)^n, counted up to coordinate permutation.

%F a(n) = Sum_{L partition of n} A348180(n, L) * A036038(len(L), sig(L)), where sig(L) is the partition composed by the part multiplicities of L.

%Y Cf. A348180, A036038, A347843, A348116-A348118.
