I'm looking at A160376, and I think the description should be "Largest prime divisor of (n!+1)..." instead of "Largest divisor of (n!+1)".  For example, 9!+1 = 362881 = 19*71*269, so the largest divisor is 71*269=19099, but the largest prime divisor is 269, which is the value in the sequence.  I think the author probably meant "Largest prime divisor", but this would make it a duplicate of A002583.

What should I do?
