Table of n, a(n) for n=0..22.

A118926 satisfies: A118926(n) = Sum_{k=0,[n/2]} A104546(n,k)*A118926(k),

where A104546(n,k) is the number of Schroeder paths of length 2n and having k platforms. Is this sequence always integer?

Cf. A118926, A104546.

Sequence in context: A247313 A262607 A059284 * A217216 A301409 A295539
