That is, the complete sequence A_n, not just the terms that are shown in the entry, does not contain a perfect square or the negative of a perfect square. (In particular, sequences containing 0 or 1 are excluded.)
No more terms up through 130. Does A000131 contain a perfect square?
I've checked A000131 up to a(25000) and can report that I found no perfect square. - Robert G. Wilson v, Jun 23 2014
