Since OEIS's superseeker in my understanding is designed to receive as
its input only terms of the strictly integral sequence (please clarify
if my understanding is wrong) - then in my opinion it will indeed be
an improvement and not a potential limitation to modify the version of
the GUESSS which is invoked by the OEIS's superseeker in the way I
