# [seqfan] Re: 2^prime(n) - prime(n^2)

```Playing with primes has no end. After a couple of minutes of playing with Mathematica I got the following which is not in OEIS either:
n*Prime[Prime[n]] - Prime[n] = 1, 7, 28, 61, 144, 233, 396, 517, 724, 1061, …

I'm wondering is it solely up to my personal judgement whether this one (or any similarly discovered) might have such a general interest that it  deserves the submission to OEIS, or is there some "moral duty" that, once discovered, also this kind of findings, kind of, ought to be? If the latter is not true, I would not submit.
