 OFFSET 1,1 LINKS EXAMPLE For 424662, the first 2 primes with the given differences are 37 and 25767877. For 646626, the least start prime is 6268957. CROSSREFS The least primes corresponding to the 6-tuples are in A078874. The same primes, in increasing order, are in A078875. The similarly defined quadruples and quintuples are in A078868 and A078870. Cf. A001223, A078869.
