COMMENTS

Let p=A001359(n-1). Then n is in the sequence if and only if we have one of constellations of eight consecutive primes: {p=30t+29 (t>=0), p+2,p+8, p+12,p+18, p+24,p+30,p+32}, {p,p+2,p+8,p+14,p+20,p+24,p+30,p+32}, {p,p+2, p+8,p+14, p+18,p+24,p+30,p+32}.

EXAMPLE

a(1)=13, then we have one of three mentioned in comment constellations of 8 consecutive primes: p=A001359(12)=149, 151, 157, 163, 167, 173, 179 and 181.
