[seqfan] Sequence with a strange for OEIS conjecture

[Vladimir Shevelev]

Dear Seq Fans,

A year ago, I introduced into OEIS sequence A174531, defined by a recursion, with a strange for OEIS conjecture:  all terms of this sequence are integers.  I wonder
1) whether exist other sequences in OEIS with such a strange for OEIS conjecture?
2) Can anyone  suggest a program for the calculation ? (the existing 42 calculated terms I found by handy).

Regards,
Vladimir
