OEIS Sequences

a(n) = n·Fibonacci(n+1). A23607

Number T(n, k) of ways to place k points on an n X n X n triangular grid so that no pair of them has distance sqrt(3). Triangle read by rows. A244500

a(1)=1, a(n) = a(n-1) + n³ if n odd, a(n) = a(n-1) + n² if n is even. A140154

Fibonacci sequence beginning 0, 17. A22351

Numbers n such that n⁴ is a sum of 4th powers of four nonzero integers whose sum is n. A138760

Natural numbers n such that the concatenations n//1331 and 1331//n are prime numbers. A174355

Positive integers k such that k = a/(b+c) + b/(a+c) + c/(a+b) for some positive integers a, b and c where the corresponding elliptic curve has rank=1. A283564

Primes p such that the concatenations p//1331 and 1331//p are both prime numbers (for naturals see A174355). A174441

Numbers k such that 3 and 6 occur juxtaposed in the base-7 representation of k but not of k+1. A43928
