Is 8795 especially uninteresting

Hi Seqfans,

prime(1097) = l(1097) + g(1097) = weight(1097) * level(1097) + g(1097).
A000040(1097) = A118534(1097) +  A001223(1097) = A117078(1097) * A117563(1097) +
A001223(1097).
8807 = 8795 + 12 = 1759 * 5 + 12.

Best,

Rémi

Andrew, thanks for catching all these duplicates.  I am slowly
working my way though them.

I'm not sure that is true!

If you still have a record of those "seven or eight pairs" please

Clark, what about this pair, are they identical?
