A periodic table of (generalised) Grassmannians.
$\mathbb{P}^{3,\vee}\hookrightarrow\mathbb{P}^{ 3 }$
The small quantum cohomology is generically semisimple.
The big quantum cohomology is generically semisimple.
The eigenvalues of quantum multiplication by $\mathrm{c}_1(\mathbb{P}^{3,\vee})$ are given by:
