OEIS Sequences

Triangle read by rows giving the coefficients of formulas generating each variety of S1(n,k) (unsigned Stirling numbers of first kind). The p-th row (p>=1) contains T(i,p) for i=1 to 2·p, where T(i,p) satisfies ∑_i=1..2·p T(i,p) * C(n,i). A94216

Indices of primes in sequence defined by A(0) = 91, A(n) = 10·A(n-1) + 71 for n > 0. A101016

Sides of squares which are filled exactly (no holes, no overlaps) by the digits needed to write a subsequence of consecutive Fibonacci numbers, starting with 0. A158027

Number of (6+2)X(n+2) 0..1 arrays with every 3X3 subblock sum of the two sums of the diagonal and antidiagonal minus the two minimums of the central column and central row nondecreasing horizontally, vertically and ne-to-sw antidiagonally. A254912

Relative of Hofstadter Q-sequence: a(n) = n for 1 <= n <= 42; a(n) = a(n-a(n-1)) + a(n-a(n-2)) for n > 42. A274055

a(n) = s(1)t(n) + s(2)t(n-1) + ... + s(k)t(n-k+1), where k = [ n/2 ], s = (natural numbers), t = (composite numbers). A24860
