The Fibonacci sequence A000045 (and any sequnce a= F(n)^k, k>=1) is
a divisibility sequence which is not in the current list because I excluded
sequences that contain zeros (as indicated in the small print of the web page);
A000045(0)=0 caused it to be ignored. I'll improve this part because
not listening that "classic" example puts shame on the entire list.
