OEIS Sequences

4-dimensional analog of centered polygonal numbers. A6322

Irregular table read by rows: Take a triangle with Pythagorean triple leg lengths with all diagonals drawn, as in A332978. Then T(n,k) = number of k-sided polygons in that figure for k >= 3 where the legs are divided into unit length parts. A333135

G.f. A(x,y) satisfies: ∑_n=-oo...+oo (xⁿ + y)ⁿ = exp( (1-y) * A(x,y) ) / (1-y), where A(x,y) = ∑_n>=1 xⁿ/n·Sum{k=0..n-1} T(n,k)*y^k, written here as a flattened triangle of coefficients T(n,k) read by rows. A321600

Number of minimal total dominating sets in the n-barbell graph. A302650

Number of (n+2) X (1+2) 0..1 arrays with each 3 X 3 subblock having clockwise perimeter pattern 00000001 00010101 or 01010101. A261285

Number of nX5 0..1 arrays with every element equal to 1, 2 or 4 king-move adjacent elements, with upper left element zero. A297855

Smallest k such that 2^k has exactly n 5's in its decimal representation. A63526
