OEIS Sequences

Number of "sets of odd lists", cf. A000262. A88009

Primes that contain digits 7 and 9 only. A20471

Primes that contain only the digits (0, 7, 9). A261181

If k is a number with exactly two distinct decimal digits, say a and b, neither of which is 0 (i.e., a member of A101594), define the self-complement of k, SC(k), to be the number obtained by replacing a with b and vice versa. E.g. SC(232233) = 323322. Sequence contains primes p such that SC(p) is also a prime. A83983

Expansion of e.g.f. exp(x/(x² - 1)). A293532

Primes with at least one digit appearing exactly four times in the decimal expansion. A161786

Centered 21-gonal primes. A276261

Near-repdigit primes with 7 as repeated digit. A105977

Transmutable primes: Primes with distinct digits d_i, i=1,m (2<=m<=4) such that simultaneously exchanging all occurrences of any one pair (d_i,d_j), i<>j results in a prime. A108388

Square array A(n,k), n >= 0, k >= 1, read by antidiagonals, where column k is the expansion of e.g.f. 1/∏_{j > 0, j mod k > 0} exp(x^j). A293530
