Properties

Appears in sequences

• Let p(k) denote k-th prime; consider solutions (p(n),p(m)) of Diophantine equation p(p(n)+1)-6.p(p(m))=1 (*), where p(p(n)) belongs to A060213 and p(p(m))=(p(p(n))+1)/6; sequence gives values of p(n).at n=10A065505
• Primes p such that p,q,r,s are consecutive primes and 2p+9, 2q+9, 2r+9, 2s+9 are also primes.at n=21A190354
• Primes which become squares when the digits are rotated once to the right.at n=37A234925
• Number of n X 3 0..1 arrays with each 1 horizontally, vertically or antidiagonally adjacent to 2 neighboring 1s.at n=13A296322
• Consecutive states of the linear congruential pseudo-random number generator (2661*s + 36979) mod 175000 when started at s=1.at n=10A385361
• Prime numbersat n=8516
