	OFFSET	`1,1`
	COMMENT	`A115230(a(n)) = 0; the union with A115232 gives all primes (A000040).`
	EXAMPLE	`A000040(35) = 149 = 2^7+37 = 2^6+517 = 2^5+3313 =` `2^4+719 = 2^3+347 = 2^2+529 = 2^1+377 = 2^0+22*37, therefore 149` `is a term (A115230(35)=0).`
	CROSSREFS	`Cf. A000079, A061345.` `Sequence in context: A128919 A100723 A031929 this_sequence A161487 A121947 A141946` `Adjacent sequences: A115228 A115229 A115230 this_sequence A115232 A115233 A115234`
