Introduction. Let Z be the set of integers Here π means the complex conjugate of π. When b ≡ 0 (mod 2) and a + b ≡ 1 (mod 4) we say that π is primary. If π or −π is primary in Z[i], then we may write π = ±π 1 . . . π r , where π 1 , . . . , π r are primary primes. For α ∈ Z[i] the quartic Jacobi symbol α
