Dear Seqfans:

This sequence (A213437 = N1082) was going to be included in the 1973
Aho-Sloane paper, but was omitted from the published version, and the
precise form of the recurrence has been lost. Like the other sequences in
that paper, the recurrence presumably has the form a(n+1) = a(n)^2 - ... In
fact a(n+1) = a(n)^2 - 2*a(n)*a(n-1) looks like a good beginning. Perhaps
someone can recover the precise recurrence from the terms provided!


Dear Friends, I have now retired from AT&T. New coordinates:
