OEIS Sequences

Triangle T, read by rows, such that T(n,k) equals the (n-k)-th row sum of T^k, where T^k is the k-th power of T as a lower triangular matrix. A91351

T(n,k) = Number of n X k 0..4 arrays with each element·equal to the number of its horizontal and vertical neighbors equal to 2,1,0,3,4 for x=0,1,2,3,4. A196436

a(n) is the number of integer partitions of n for which the Kimberling index is equal to the index of the seaweed algebra formed by the integer partition paired with its weight. A318177

Row sums of the matrix square of triangle A091351, in which the k-th column lists the row sums of A091351^k (the k-th power of A091351 when considered as a lower triangular matrix). A91353

Triangular matrix T, read by rows, that satisfies: SHIFT_LEFT_UP(T) = T² - T + I, or, equivalently: T(n+1,k+1) = [T²](n,k) - T(n,k) + [T⁰](n,k) for n>=k>=0, with T(0,0)=1. A104445
