Wait a second!
The A087851 formula is for A087851, and the values given for that
sequence are correct.

A087852 and A087853 should both be just dead, in my opinion.  There's
no real merging to be done with them since their "recursive"
definitions refer to later terms instead of earlier ones.

Thanks!

when the OEIS reached 100000 sequences we had an e-party: to

I would like to invite those who missed it to join now!

I think it adds greatly to the database to see the other contributors
and where in the whole world they live.

So send me a photo, etc. - see the existing party pages for the style.

I'm sending this also to a few people who are not on the seqfan list.
We are, after all, all friends here.
