%N A077038 Least difference of primes p, q such that p < n^3 < q.
%C A077038 Least m such that a(m)=2*n for n=1,2,3,... are: {2,3,14,7,6,5,15,28,21,24,13,...}. - _Zak Seidov_, May 10 2016
%C A077038 There are numbers k other than 2 such that a(k) = 4. The first few (up to 1000) are 129 189 369 435 549 555 561 819. Conjecture: every even integer greater than 2 occurs infinitely often in this sequence. - _Franklin T. Adams-Watters_, May 13 2016
