Primality
- Prime
- yes
Appears in sequences
- Primes that contain digits 1 and 3 only.at n=29A020451
- 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.at n=39A083983
- Smallest prime obtained by sandwiching prime(n) between identical digits, except that a(5) = 0.at n=5A090268
- Smallest prime obtained by sandwiching n between a number with identical digits, or 0 if no such prime exists. Primes of the form k n k where all the digits of k are identical.at n=13A090287
- Near-repdigit primes with 3 as repeated digit.at n=30A105981
- List the first term of each triple of consecutive primes with the property that their sum is the square of a prime.at n=17A130621
- Primes with at least one digit appearing exactly five times in the decimal expansion.at n=13A161796
- Smallest of three consecutive primes whose sum is a square.at n=29A206279
- Smallest members of prime triples, the sum of which results in a perfect square.at n=10A309594
- Primes consisting of a single 1 and at least one copy of some other digit.at n=30A325934
