Properties

Appears in sequences

• Primes that remain prime through 4 iterations of function f(x) = 6x + 5.at n=39A023317
• n is prime and is the concatenation of numbers n_1, n_2, n_3, in that order, with n_1 - n_2 = n_3. (Do not allow leading zeros for nonzero n_i.)at n=41A067861
• Consider numbers of the form ...7531975319753197, whose digits read from the right are 7,9,1,3,5,7,9,1,3,5,7,... Sequence gives lengths of these numbers that are primes.at n=17A090745
• Primes p such that the left prime neighbors p1, p2 of p as well as the right prime neighbors q1, q2 of p form twin prime pairs and the sum p1 + p2 + p + q1 + q2 is also prime.at n=26A138396
• Primes p such that each decimal digit of p is equal to the difference of two other digits of p.at n=36A255892
• Partial sums of the number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 561", based on the 5-celled von Neumann neighborhood.at n=35A272937
• Primes having only {0, 4, 7} as digits.at n=6A384449
