Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N Primes at which the difference pattern X42Y (X and Y >= 6) occurs in A001223.
%e 67 is in the sequence because 67 + 4 = 71 and 67 + 4 + 2 = 73 are primes, the prime prior to 67 is 61, the prime after 73 is 79, and the corresponding differences are 6 and 6. The d-pattern "around 67" is {6,4,2,6}.
%Y Cf. A001223, A051260.
