OEIS Sequences

Fibonacci sequence beginning 4,9. A22130

Triangle T(n,k), n >= 2, 0 <= k <= floor(n²/2)-2·n+2, read by rows, where T(n,k) is the number of 2*(k+2·n-2)-cycles in the n X n grid graph which pass through four corners ((0,0), (0,n-1), (n-1,n-1), (n-1,0)). A333668

Values of·in the solutions to x² - 3xy + y² + 29 = 0, where 0 < x < y. A218735

Irregular triangular array: row n gives numbers D, each being the discriminant of the minimal polynomial of a quadratic irrational represented by a continued fraction with period an n-tuple of 1s and 3s. A246921

Irregular triangular array: every periodic simple continued fraction CF represents a quadratic irrational (c + f·sqrt(d))/b, where b,c,f,d are integers and d is squarefree. Row n of this array shows the distinct values of d as CF ranges through the periodic continued fractions having period an n-tuple of 1s and 3s. A246922

Number of 2 X 2 regular integer matrices with elements from {0,...,n} up to row and column permutation. A64363
