OEIS Sequences

T(n,k) = binomial(n-floor((k+1)/2), floor(k/2)). Triangle read by rows, for 0 <= k <= n. A65941

A Collatz-Fibonacci mixture: a(1) = 1, a(2) = 2, a(n+2) = a(n+1)/2+a(n)/2 if a(n+1) and a(n) have the same parity, a(n+2) = a(n+1)+a(n) otherwise. A69202

G.f. satisfies: A(x,y) = 1 + ∑_n>=1 xⁿ*y·A(x,y)ⁿ/(1 - y·A(x,y)^2·n), where A(x,y) = 1 + ∑_n>=1,k>=1 T(n,k)*xⁿ*y^k; here the coefficients T(n,k) form a square array and are read by antidiagonals. A192404
