OEIS Sequences

a(n) = largest number of distinct words arising in Post's tag system {00, 1101} applied to a binary word w, over all starting words w of length n, or a(n) = -1 if there is a word w with an unbounded trajectory. A284116

Triangle T(n,k), 0 <= k <= n, read by rows, defined by T(0,0) = 1; T(0,k) = 0 if k>0 or if k<0; T(n,k) = k·T(n-1,k-1) + (k+1)*T(n-1,k+1). A104035

a(n) = 3·a(n-1) - 2·a(n-2) with a(0)=16 and a(1)=40. A182461

E.g.f.: sec(x)²*tan(x)+sec(x)*tan(x)². A225689

T(n,k) = Number of n X k 0,1 arrays indicating 2 X 2 subblocks of some larger (n+1) X (k+1) binary array having two adjacent 1's and two adjacent 0's. A227442

E.g.f. C(x,y) = cos(y) / sqrt(1 - sin(x)² - sin(y)²). A324609

Triangle T(n,k) (n>=0, 0<=k<=n) read by rows: T(0,0)=T(1,1)=1; T(n,0) is the Euler number A000111(n-1) for n>=1; T(n,n-1) = T(n,n) = (n-2)! for n>=2; interior entries are given by T(n,k) = m·T(n-1,k-1)+(k+1)*T(n-1,k+1) where m = k if n+k is even or k-1 if n+k is odd. A350970

E.g.f. C(y,x) = cos(x) / sqrt(1 - sin(x)² - sin(y)²). A324611
