Table of n, a(n) for n=0..101.

a(n) = A125989(A014486(n)).

A014486(2) = 10 (1010 in binary) which encodes Dyck path /\/\ with two peaks at height=1, thus a(2)=2.

a(n) = a(A125976(n)) for all n.

Sequence in context: A271237 A062558 A072789 * A200648 A264982 A134674

Adjacent sequences: A126299 A126300 A126301 * A126303 A126304 A126305
