Examples

			a(1) = 3969 as there are exactly two distinct totally real cubic fields both with discriminant 3969, namely Q[x]/(x^3 - 21*x - 28) and Q[x]/(x^3 - 21*x - 35). - _Robin Visser_, Apr 18 2025

In Ennola et al., 431649 is listed twice, because there are two such fields with that discriminant.
