OEIS Sequences

Consider the Diophantine equation x³ + y³ = z³ - 1 (x < y < z) or 'Fermat near misses'. The values of z (see A050787) are arranged in monotonically increasing order. Sequence gives values of y. A50789

a(n) = 81·n² - 72·n + 17. A154277

Array read by antidiagonals: Place k points in general position on each side of a regular n-gon and join every pair of the k·n boundary points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of vertices in the resulting planar graph. A392261

a(n) = 4·prime(n)²+1. A60429

Numbers k such that C(k+2,2) divides 2^k+1 - 1. A246636

Expansion of 1/(1 - x/(1 - x/(1 - x²/(1 - x/(1 - x³/(1 - x/(1 - x⁴/(1 - ...)))))))), a continued fraction. A296201

Prime numbers of the form (2^k + k²)/3. A270818

a(n) = Sum(a(2i-1)*a(n-2i+1), i = 1,2,...,[ (n+2)/4 ]). A24965
