Hi Claudio,
Yes - I realize that. It was clarified several messages prior in response
to questions by others. I sent my inquiry right after your message posted,
and mine was delayed for some reason (which happens sometimes) and posted
out of order. Did you receive my off-list messages from April 5? You can
reply directly off-list, too.
Anyway, A284919 is a quite interesting sequence! (BTW - I made a minor
correction there - ironically, a comment omitted that BOTH E+p and E+q are
composite).
Cheers,
Bob S
