 OFFSET 1 LINKS Antti Karttunen, Table of n, a(n) for n = 1..100000 FORMULA a(n) = A353348(n) mod 2. a(n) = a(A003961(n)) = a(A348717(n)), for all n >= 1. a(n) <= A353350(n). [Follows because A332820 is a multiplicative semigroup. See comments in A353348] PROG (PARI) A359826(n) = (A353348(n)%2); CROSSREFS Characteristic function of A359827. Cf. A003961, A048675, A332820, A353348, A353350. Cf. also A359836.
