OEIS Sequences

Triangle read by rows: T(n,k) is the number of permutations of {1,2,...,n} having k doubledescents (0 <= k <= n-2). We say that i is a doubledescent (also called a double fall) of a permutation p if p(i) > p(i+1) > p(i+2). A162975

Number of face-connected components of triakis truncated tetrahedral cells in the triakis truncated tetrahedral honeycomb up to translation, rotation, and reflection of the honeycomb. A385027

T(n,k)=Number of nXk 0..3 arrays with no element x(i,j) adjacent to value 3-x(i,j) horizontally, diagonally or antidiagonally, top left element zero, and 1 appearing before 2 in row major order. A233098

T(n,k)=Number of nXk 0..2 arrays with rows and columns in lexicographic nondecreasing order but with exactly one mistake. A278309

Number of partitions p of n such that median(p) > mean(p). A240220

Numbers k such that (k+3, k+5, k+17, k+257, k+65537) are all primes. A63799

Number of permutations of [n] having exactly five (possibly overlapping) doubledescents. A279294

Semiprimes s = A001358(k) such that k, s - k and s + k are also semiprimes. A383468
