Lists of negative discriminants by class group?

189 Views Asked by At

Is there a handy listing of the discriminants of imaginary quadratic fields having a given ideal class group? It would be nice to use such a resource as a source of examples.

For example, we're all set for class number $4$:

  • A013658 Discriminants with class number $4$

If we want just the cyclic or the non-cyclic groups, we can intersect with these lists:

  • A227735 Discriminants with cyclic class groups of composite order
  • A227734 Discriminants with noncyclic class groups

The latter of which results in:

  • A192322 Discriminants whose class group is the Klein $4$-group, $C_2\times C_2$

So that's really convenient! But are there also pre-computed lists to distinguish, say, $C_2\times C_2\times C_2$ from $C_4\times C_2$?

(The closest resource I've found is A225365 Discriminants with non-isomorphic class groups, which is still a great source of examples, if not exhaustive.)
