S000321

The offsets (5, 7, 11, 13, 17) are prime. This sequence a subset of S000320. This is the last such sequence beginning with 5; for a sequence starting with 6 consecutive primes, we need to start with 7. Suggested in the paper by Granville. Sequence S000322 lists the initial prime and the last possible prime. So {5, 17}, illustrated in this sequence, occurs in that sequence.
