Properties

Appears in sequences

• Primes that remain prime through 5 iterations of function f(x) = 2x + 5.at n=20A023332
• Consider all integer triples (i,j,k), j >= k > 0, with binomial(i+2,3)=j^3+k^3, ordered by increasing i; sequence gives j values.at n=28A054206
• On a spirally numbered square grid, with labels starting at 0, this is the number of the final step that a (1,n) leaper makes before getting trapped, or -1 if it never gets trapped.at n=18A323470
• Prime numbersat n=21076
