 A079010 a(n)=nextprime[16+A022008(n)]-(16+A022008(n)); a(n) is the prime difference d>=6, following [42424] difference pattern defining A022008. 0

 OFFSET 1,1 LINKS EXAMPLE n=2: A022008(2)=97, corresponding sextuplet is {97,101,103,107,109,113=97+16}, nextprime[113]-113=127-113=14, so a(2)=14. Constraints for present terms: (a) are incongruent to 4 modulo 6; (b) Mod[a(n),30]={0,6,8,14,18,20,24,26}; 6 occurs only once; (c) further prohibited values like e.g. 20 etc. MATHEMATICA d[x_] := Prime[x+1]-Prime[x] h={k1=4, k2=2, k3=4, k4=2, k5=4} k=0; Do[If[Equal[d[n], 4]&&Equal[d[n+1], 2]&& Equal[d[n+2], 4]&&Equal[d[n+3], 2]&& Equal[d[n+4], 4], Print[d[n+5]]], {n, 1, 100000}] CROSSREFS Cf.
