 OFFSET 1,1 LINKS This sequence gives the increasingly ordered primes of the form k(m) + k(m+2) with k(m) = A018252(m). The m values are    1, 14, 24, 37, 56, 60, ... EXAMPLE a(1) = 7 is the smallest prime of the mentioned form, obtained for m=1: A018252(1) + A018252(3) = 1 + 6 = 7. a(2) = 47 is the second smallest prime of this form, with m = 14:  A018252(14) + A018252(16) = 22 + 25 = 47. PROG (MAGMA) m:=1500; NonPrime:=[i: i in [0..m] | not IsPrime(i)]; [q: n in [2..#NonPrime-1] | IsPrime(q) where q is NonPrime[n-1]+NonPrime[n+1]]; CROSSREFS Cf. A018252, A167611.
