OEIS Sequences

Nontrivial odd solutions n to P(n) == 1 + r*∑_i=1..d(n) xⁱ (mod m) where P(n) is the n-th Stern polynomial, d(n) is the degree of P(n), r=2, m=3. A327850

a(0) = 1; for n>0, a(n) is taken to be the smallest positive integer greater than a(n-1) which is consistent with the condition "n is a member of the sequence if and only if a(n) == 1 mod 3". A80723
