OEIS Sequences

Primes that contain digits 1 and 7 only. A20455

Primes having only {0, 1, 7} as digits. A199327

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

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

Primes of the form 7n² - 4. A201850

Numbers k such that the "inventory" A063850 of k is a perfect square. A79465

Number of walks within N³ (the first octant of Z³) starting at (0,0,0) and consisting of n steps taken from {(-1, -1, 0), (-1, 0, 0), (0, 0, -1), (1, -1, 0), (1, 1, 1)}. A149665

a(n) = k where k! is the product of the terms of the n-th row of A077168. A77171
