SeqFans, Neil,

yes I can confirm that the virus scanner seems even to block regular
mails sent to Neil. I just tried to send an e-mail to Neil. I got the
attached reply.

The content of the message was as follows:


after reading your message about the troubles with the submit webpage, I
checked my last submissions and found that A112859, that I had submitted
via the webpage form has not made into the database.
But the reason might be different from the current problem. I tried to
reconstruct what could have happened and found that after reserving a
range of A-numbers:

Email address: hugo at
Remote address:
QQQ%%%ZZZ got 12 numbers, 112853 through 112864. Next free
is 112865

I probably had a typo in my E-mail address that I used during the
submission (hugop at instead of hugo at

When I noticed that I didn't get the usual confirmation e-mail, I
resubmitted the sequence, this time with the correct e-mail address, but
again no reply. It seems to me that the wrong e-mail used for a
dispenser supplied A-number creates a permanent blockade thus locking
the A-number for a resubmission by the person that had reserved the
A-number range.

Could you please add the attached sequence manually?

Thanks and best regards


%I A112859
%S A112859
%N A112859 Numbers n such that (2*n)!/(n!)^2+1 is prime.
%C A112859 The next term is > 11400.
%Y A112859 Cf. A112860 primes of the form (2*n)!/(n!)^2+1, A112853
(2*n)!/n!-1 is prime, A112855 (2*n)!/n!+1 is prime, A112857
(2*n)!/(n!)^2-1 is prime, A112861 (2*n)!/(2*(n!)^2)-1 is prime, A112863
(2*n)!/(2*(n!)^2)+1 is prime.
