Consists of a scheme $X$, satisfying the following properties:

$X$ separated, not noetherian, cohen-macaulay, all stalks of the structure sheaf are domains, not integral, locally noetherian, dimension 0, regular, not connected, not quasi-compact, not irreducible, excellent, not affine, all stalks of the structure sheaf are irreducible, finite dimensional, normal, reduced

By the theorems, we also have {"X": {"quasi-separated": true}}
