a(n) = a(n-1) + a(n-2) - [a(n-2)/4] - [a(n-4)/2] - [a(n-6)/4]. A173599

Triangle read by rows: T(n,k) (n >= 1, 3 <= k <= n+2) = number of k-sided cells in the n-th figure shown in A255011 (meaning the figure with 4n points on the perimeter). A334699

a(n) = n! * ∑_{0<=i<=j<=k<=n, i+j+k<=n} 1/(i!*j!*k!). A76177

a(n) = sum of numbers formed using the digits of next n numbers. A81993

Triangle read by rows which contains in row n that permutation of the n numbers T(n-1)+1..T(n) which yields a smallest multiple of n after concatenation. T(n) are the triangular numbers. If no such multiple exists, the row contains zeros. A96135

Concatenation of the terms of the n-th row in A096135, divided by n. A96136

Number of 1's in the base 8 form of A077722(n). A79108

Triangle t(n,m) = p(n)/ (p(m)*p(n-m) ) read by rows, where p(n>=1) = 1, -1, 2, 10, 10, -160, -2080,.. are partial products of A106852. A177694
