	OFFSET	`2,2`
	COMMENT	`A064802 gives next larger comparable number. Ratio of a(n) to n is ratio of successive primes (n>2).`
	EXAMPLE	`a(18)=12 because 18=233 and net smaller comparable factorization is 22*3=12.`
	CROSSREFS	`Cf. A094456 A064802 A094521.` `Sequence in context: A031233 A030584 A030564 this_sequence A022820 A069928 A135585` `Adjacent sequences: A094454 A094455 A094456 this_sequence A094458 A094459 A094460`
