FORMULA

a(n) = a(n-1)+A055881(n).

a(n) = (e-1)*n + f(n) where f(n) < 0. - Benoit Cloitre (benoit7848c(AT)orange.fr), Jun 19 2002. Comment from Franklin T. Adams-Watters, Nov 03 2005: f is unbounded in the negative direction. The assertion that f(n) < 0 is correct, since (e-1)*n = sum_{k=1}^{infinity} n/k! is term for term >= this sequence.
