OEIS Sequences

Triangle read by rows: Eulerian numbers of type B, T(n,k) (1 <= k <= n) given by T(n, 1) = T(n,n) = 1, otherwise T(n, k) = (2·n - 2·k + 1)*T(n-1, k-1) + (2·k - 1)*T(n-1, k). A60187

a(n) = binomial(n+3, 3)/4 for odd n, n*(n+2)*(n+4)/24 for even n. A6918

a(n) = 2·binomial(n,3). A7290

Denominators of Cauchy numbers of first type. A6233

Triangle read by rows: T(n,c) = number of successive equalities in set partitions of n. A56857

a(n) = σ(n) * A003961(n), where A003961 shifts the prime factorization of n one step towards larger primes, and σ is the sum of the divisors of n. A341529

Table T(n,k) by antidiagonals. T(n,k) is the number of length n primitive (=aperiodic or period n) k-ary words (n,k >= 1) which are earlier in lexicographic order than any other word derived by cyclic shifts of the alphabet. A143325

Denominators of Cauchy numbers of second type (= Bernoulli numbers B_n⁽ⁿ⁾). A2790

Number of 6-ary Lyndon words of length n with trace 0 and subtrace 0 over Z₆. A74422
