Properties

Appears in sequences

• Primes that contain digits 1 and 5 only.at n=13A020453

• a(n) is the least prime > a(n-1) whose digits do not appear in a(n-1).at n=36A030284
• Multiplicative primes: product of digits is a prime.at n=29A046703
• Smallest multidigit prime such that the sum of the squares of its digits is equal to n times the product of its digits, or 0 if no such prime exists.at n=5A067791
• Primes formed by a 5 followed by 1's.at n=0A068816
