	OFFSET	`1,2`
	EXAMPLE	`n=10: C(10,5)=252=22337. The largest square-free number dividing the 10th central binomial coefficient is 237=42. Thus a(10)=42`
	CROSSREFS	`Equals A007947(A001405(n)). Cf. A034973.` `See A056058 for another version.` `Sequence in context: A056060 A056058 A028255 this_sequence A047402 A088196 A112925` `Adjacent sequences: A048630 A048631 A048632 this_sequence A048634 A048635 A048636`
