A. Karttunen and J. Moyer, C-program for computing the initial terms of this sequence
Index entries for sequences related to occurrences of various subsets of primes in range ]2^n,2^(n+1)]
a(n) = A036378(n)-A095016(n) (apart the initial term).
Sequence in context: A245738 A133044 A014529 * A024367 A232432 A037078
