 OFFSET 0,5 COMMENTS Diving index of an odd number n is the first integer u > 1 where Sum_{i=1..u} J(i/n) results -1 and zero if never. Here J(i/n) is Jacobi symbol of i and n, which reduces to a Legendre symbol L(i/n) when n is a prime. LINKS A. Karttunen and J. Moyer, C-program for computing the initial terms of this sequence CROSSREFS a(n)=A095270(n)+1 modulo A004767(n). Cf. A095109, A095271 (same sequence with zeros removed).
