OEIS Sequences

Triangle read by rows: T(n, m) = number of forests with n nodes and m labeled trees. Also number of forests with exactly n - m edges on n labeled nodes. A105599

Triangle read by rows: T(n, k) is the number of forests on n labeled nodes with k edges. T(n, k) for n >= 1 and 0 <= k <= n-1. A138464

Triangle read by rows: T(n,k) is the number of permutations of {1,2,...,n} having k increasing even cycles (0<=k<=n). 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 even if it has an even number of entries. For example, the permutation (18)(2347)(569) has 2 increasing even cycles. A186764

Sum of all the parts in the partitions of n into 9 squarefree parts. A326523

Triangle read by rows giving the coefficients of general sum formulas of n-th Fibonacci numbers (A000045). The k-th row (k>=1) contains T(i,k) for i=1 to 2·k-1, where T(i,k) satisfies F(n) = ∑_k=1..n ∑_i=1..2·k-1 T(i,k) * C(n-k,i-1) * n^n-k / (n-1)!. A100492

Numbers k with digits 5 and 7 only. A284380
