OEIS Sequences

Numbers n such that n²⁰⁴⁸ + 1 is prime (a generalized Fermat prime). A88361

Number of (s(0), s(1), ..., s(2n)) such that 0 < s(i) < 8 and |s(i) - s(i-1)| = 1 for i = 1,2,...,2n, s(0) = 1, s(2n) = 3. A94803

Place n equally spaced points on each side of an equilateral triangle, and join each of these points by a chord to the 2·n new points on the other two sides: sequence gives number of regions in the resulting planar graph. A366486

Decimal representation of the diagonal from the corner to the origin of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 214", based on the 5-celled von Neumann neighborhood. A286736

For 1<=x<=n, 1<=y<=n, write gcd(x,y) = u·x+v·y with u,v minimal; a(n) = sum of the values of |v|. A345433

Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of these n·k points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of regions in the resulting planar graph. A367304

Expansion of ((sqrt(2)-1)*(-sqrt(2);x)_inf - (sqrt(2)+1)*(sqrt(2);x)_inf)/2, where (a;q)_inf is the q-Pochhammer symbol. A278296

Total number of binary digits used to write all partitions of n in binary notation. A318756

a(n) = 289n + 1. A158255

Number of tilings of a 5 X n rectangle using n pentominoes of shapes P, I, N, T. A246764
