OEIS Sequences

Catalan numbers: C(n) = binomial(2n,n)/(n+1) = (2n)!/(n!(n+1)!). A108
The squarefree numbers ordered lexicographically by their prime factorization (with factors written in decreasing order). a(n) = ∏k in I prime(k+1), where I is the set of indices of nonzero binary digits in n = ∑k in I 2k. A19565
a(n) = n*(n+3)/2. A96
Triangle formed from even-numbered columns of triangle of expansions of powers of·in terms of Chebyshev polynomials Un(x). A39599
Number of (0,1) matrices with n ones and no zero rows or columns, up to row and column permutations. A49311
Catalan's triangle T(n,k) (read by rows): each term is the sum of the entries above and to the left, i.e., T(n,k) = ∑j=0..k T(n-1,j). A9766
