Abstract
Suppose p is a positive prime number congruent to 1 modulo 3. Then, as is well known, one can write \( 4p = {L^2} + 27{M^2} = \lambda \bar \lambda ,{\text{ where }}\lambda = L + 3M\sqrt { - 3} ,L,M \in Z,L \equiv 1\left( {\bmod 3} \right),L \equiv M \) (mod 2). The integers L and M are uniquely determined by these conditions. For n ≥ 1, write 4p n = f n(L, M)2 + 27 g n(L,M)2, f n (L, M) and g n (L,M) being rational integers defined by
