 kis 4-dihedron and the cube is a truncated 4-hosohedron.
 This is interesting because the octahedron is also an ambo tetrahedron,
 and the cube a join tetrahedron: if we admit degenerate polyhedra,
-there are some polyhedra with two unequal reductions into operators and seeds.

+We can also apply AEROs: an n-sided pyramid is an alternating-truncated n-hosohedron.

 Operators may also be applied to surfaces with boundary, although the behavior
 of the operator at the boundary needs to be specified. In general,
