Appears in sequences

• Primes of the form k^2 + 5.at n=13A056905
• Numbers n such that n*359# +-1 are twin primes, where 359# = 72nd primorial (A002110(72)).at n=32A087907
• Consider primes p such that integer part of the volume of cube with faces of area p is prime; sequence gives integer part of volumes.at n=18A107989
• Primes p1 such that p1^3+p2^2=pp are average of twin primes. p1 and p2 consecutive primes, p1 < p2.at n=24A138735
• Primes of the form (5+ a triangular number A000217).at n=32A159049
• Take A163498(n) written in binary, insert a 0 before every 1. a(n) is the decimal equivalent of the result.at n=41A163499
• Number of emergent parts in all partitions of n.at n=40A182699
• Number of partitions of n^3 into squares.at n=6A218494
• Replacing each digit d in decimal expansion of n with d^2 yields a prime at each step when done recursively three times.at n=31A316604
• Prime numbersat n=4354
