OEIS Sequences

Main diagonal of the array in which first column and row are filled alternatively with 1's or 0's and then T(i,j) = T(i-1,j) + T(i,j-1). A72547

a(n) = n·Fibonacci(n). A45925

Regular triangle read by rows where T(n,k) is the number of set partitions of {1,...,n} with k topologically connected components. A324173

Triangle read by rows: T(n,k) is the number of permutations of {1,2,...,n} having k nonincreasing odd cycles (0<=k<=floor(n/3)). A cycle (b(1), b(2), ...) is said to be increasing if, when written with its smallest element in the first position, it satisfies b(1)<b(2)<b(3)<... . A cycle is said to be odd if it has an odd number of entries. For example, the permutation (152)(347)(6)(8) has 1 nonincreasing odd cycle. A186766

Result of using the perfect squares as coefficients in an infinite polynomial series in·and then expressing this series as (1+a(1)x)(1+a(2)x²)(1+a(3)x³)... A147559
