“Everything should be made as simple as possible, but no simpler.”

I tend to see things differently...

--Amateur number theorist and empiricist

--Loves coding and computation

--Believes in the value of parsimony and elegant solutions

A140947 Four-columned array read by rows: each row gives a series of 4 consecutive primes that share a 2nd-degree polynomial relationship and produce a positive-only integer series from the derived quadratic.

A134969 List of pairs of primes that are separated by the equivalent of 2 quadratic intervals. Both primes are greater than their preceding perfect squares by the same amount, or offset. The respective perfect squares can be both odd, in which case the offset is even, or both even, in which case the offset is odd.

A155557 A "proximate-prime polynomial" sequence generated by 2*n^2 - 2*n + 53089. Produces 634 primes in the first 1000 terms.

Some more PPPs: A126719 a(n) = -n^2 + 9n + 23, A126665 a(n) = -n^2 + 9n + 53, A127316 a(n) = 2*n^2 - 4*n + 73.
