OEIS Sequences

Inverse binomial transform of the number of planar partitions (A000219). A294501

a(n) = ((1 - sqrt(3))ⁿ + (1 + sqrt(3))ⁿ)/2^floor((n - 1)/2); n-th row common denominator of A321118. A321119

t(n²) is a square and sets a new record for such squares, where t(n) = (σ(n)-n)*ω(n); or t(n)= A001065(n)*A001221(n). A63777

a(n) is the number of perfect matchings of an edge-labeled 2 X n Klein bottle grid graph, or equivalently the number of domino tilings of a 2 X n Klein bottle grid. (The twist is on the length-n side.) A351635

a(0) = a(1) = a(2) = 1; thereafter odd indexed terms are the sum of the last 3 terms and even indexed terms are the sum of all previous terms. A393527
