Dear Seqfans,

There is an interesting sequence of Eric Wegrzynowski:

I just submitted to the OEIS:

%I A000001
%S A000001 3125,1075,985,580,1281,295,1305,580,925,631,1305,220,1305,655,901,580,1305,295,1305,556,925,655,1305,220,1281,655,925,580,1305,271,1305,580,925,655,1281,220,1305,655,925,556,1305,295,1305,580,901,655,1305,220,1305,631,925,580,1305,295,1281,580,925,655,1305,196,1305,655,925,580,1281,295,1305,580,925,631,1305,220,1305,655,901,580,1305,295,1305,556,925,655,1305,220,1281,655,925,580,1305,271,1305,580,925,655,1281,220,1305,655,925,556,1305
%N A000001 Let a(n,m) = card{f^(n) : f is a mapping from a set of m elements into itself}, where f^(l)(x) = f^(l-1)(f(x)),l>0, f^(0)(x) = x; sequence gives a(n,5).
%Y A000001 Cf. A102687.
%O A000001 1
%K A000001 ,nonn,


Best regards to all,
