	OFFSET	`0,3`
	FORMULA	`a(n) = A125989(A014486(n)).`
	EXAMPLE	`A014486(2) = 10 (1010 in binary) which encodes Dyck path /\/\ with two peaks at height=1, thus a(2)=2.`
	CROSSREFS	`a(n) = a(A125976(n)) for all n.` `Sequence in context: A073734 A062558 A072789 this_sequence A134674 A000121 A049846` `Adjacent sequences: A126299 A126300 A126301 this_sequence A126303 A126304 A126305`
