OEIS Sequences

Expansion of (1 - x - x² + sqrt((1 - x - x²)² - 4·x³))/2 in powers of x. A292461

Generalized Catalan numbers: a(n+1) = a(n) + ∑_k=1..n-1 a(k)*a(n-1-k). A4148

Triangle read by rows: T(n,k) is the number of weighted lattice paths in L_n having k (1,-1)-returns to the horizontal axis. The members of L_n are paths of weight n that start at (0,0), end on the horizontal axis and whose steps are of the following four kinds: an (1,0)-step with weight 1, an (1,0)-step with weight 2, a (1,1)-step with weight 2, and a (1,-1)-step with weight 1. The weight of a path is the sum of the weights of its steps. A182896

Expansion of (1 - x - x² - sqrt((1 - x - x²)² - 4·x³))/(2·x³) in powers of x. A292460

Number of elevated peakless Motzkin paths. A203019

Number of 3X3X3 triangular 0..n arrays with no element lying outside the (possibly reversed) range delimited by its sw and se neighbors, and every horizontal row having the same average value. A214541

Number of (n+2) X (1+2) 0..1 arrays with each 3 X 3 subblock having clockwise perimeter pattern 00000101 00010001 or 00010101. A260602
