[seqfan] PrimeGrid's GFN mega prime and A056993

Dear SeqFans,

after PrimeGrid's find (see
http://www.primegrid.com/forum_thread.php?id=7597), 919444 was added to
A056993, but then removed and a comment added that "919444 is also a
member, but may not be the next term".

How is that statement correct? If n=20 has a b with 1 < b < 919444, then
a(20) = b and 919444 isn't a term of the sequence at all.

I think the comment should be corrected.

Best regards
Felix Fröhlich
