Alois P. Heinz, Table of n, a(n) for n = 0..444
FORMULA
E.g.f.: exp(Sum_{j=1..5} (exp(j*x)-1)/j).
MAPLE
b:= proc(n, m) option remember; `if`(n=0, 1,
add(b(n-1, max(m, j)), j=1..m+5))
end:
a:= n-> b(n, 0):
seq(a(n), n=0..25);
# second Maple program:
a:= n-> n!*coeff(series(exp(add((exp(j*x)-1)/j, j=1..5)), x, n+1), x, n):
seq(a(n), n=0..25);
