(In reply to re: Go on, indeed. by broll)

OEIS is a great site. I'm sure I've referenced it more than twice. Have I disparaged using it it in the past? I hope not, I visit there probably once a week.

Just posting a link to OEIS as a solution isn't doing much for the problem, but I feel I went a bit beyond the OEIS sequence. Plus the OEIS sequence is not the same as Ady's - it just contains Ady's.
