%N a(n) = n*(a(n-1)-1) starting with a(0)=3.
%C Starting with a(0)=0 would give -A007526(n); starting with a(0)=1 would give -A038156(n). In general, for this recurrence, a(n) = ceiling(1 + n!*(a(0)-e)) for n>0; this is the first case with positive terms.
%F a(n) = ceiling(1 + n!*(3-e)) for n>0.
%F a(n) = n! - floor(e*n!) + 1, n>0. - _Gary Detlefs_, Jun 06 2010
