OEIS Sequences

Number T(n,k) of n-step walks on cubic lattice starting at (0,0,0), ending at (0,k,n-k), remaining in the first (nonnegative) octant and using steps (0,0,1), (0,1,0), (1,0,0), (-1,1,1), (1,-1,1), and (1,1,-1); triangle T(n,k), n>=0, 0<=k<=n, read by rows. A328300
Decimal representation of the diagonal from the corner to the origin of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 353", based on the 5-celled von Neumann neighborhood. A287759
a(n) = (27·n2 + 9·n + 2)/2. A93485
Triangle read by rows: CP(n,i) for n>=0 and 3n+1 >= i >= 0, gives the absolute value of the coefficients of the chromatic polynomial of C3 X Pn+1 factored in the form x(x-1)i. A123531
Semiprime centered triangular numbers. A184481
Numbers n such that the Collatz iterations for n and n + 1 have the same length (A078417) but do not meet a certain condition. (See comments.) A274410
Discriminants of real quadratic fields with class number 2 and related continued fraction period length of 21. A51986
a(n) = a(n-1) + a(n-2) + a(n-3) + R(a(n-4)) where a(0)=a(1)=a(2)=a(3)=1 and R(n) (A004086) is the reverse of n. A74863
a(n) = a(n-1) - a(n-2) if n is prime or a(n-1) + a(n-2) otherwise. a(1) = a(2) = 1. A192439
Partial sums of the number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 718", based on the 5-celled von Neumann neighborhood. A273427
