[seqfan] Re: A140870 & A050216

Arguably, A140870 is the more correct version; it includes the two 
primes before p(1)^2.  Thus A000879 is the cumulative sums of A140870, 
and not of A050216.

I would be inclined to add the initial 2 to A050216, change the offset 
to 0, and add a comment explaining what a(0) means.  Then A140870 can 
be removed.  The crossref in A000879 can be changed to: cumulative sums 
of A050216.

Isn't A140870
a wrong version (extra initial 2)
of A050216?
