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.
