OEIS Sequences

Number A(n,k) of n-member subsets of [k·n] whose elements sum to a multiple of k; square array A(n,k), n>=0, k>=0, read by antidiagonals. A318557

This table shows the coefficients of sum formulas of n-th Fibonacci numbers (A000045). The k-th row (k>=1) contains T(i,k) for i=1 to k, where k=[2·n+1+(-1)^n-1]/4 and T(i,k) satisfies F(n)= ∑_i=1..k T(i,k) * n^k-i/(k-1)!. A99731

Numbers which are the sum of their proper divisors containing the digit 0. A59461

Numbers k such that k²-1 and k²+1 are semiprimes. A108278

T(n,k)=Number of nXk 0..1 arrays with every element equal to 0, 1, 2, 3, 5, 6, 7 or 8 king-move adjacent elements, with upper left element zero. A300267

Number T(n,k) of plane partitions of n into parts of exactly k sorts which are introduced in ascending order; triangle T(n,k), n>=0, 0<=k<=n, read by rows. A319730

Squarefree numbers sandwiched between a pair of twin primes. A70195

Least k such that k·12ⁿ +/- 1 are twin primes. A64221

Numbers k such that (10^2·k+1 + 36·10^k - 1)/9 is prime. A107125
