The double Hessian polyhedron is a regular complex polyhedron. It's vertices are equivalent to a pair of dual Hessian polyhedra.

The relationship between the three Platonic solids (left), and the analygous relationship between the three Hessian polyhedra (right)

The three regular complex polyhedra:

share analogous relationships to three Platonic solids:

1. the tetrahedron
2. the cube
3. the octahedron

Those relationships are:

• 1 is self-dual.
• 2 is dual to 3.
• 1 is the halving of 2.
• 3 is the rectification of 1.

If the vertices of the Double Hessian polyhedron are treated as vertices in ${\displaystyle \mathbb {R} ^{6}}$ rather than ${\displaystyle \mathbb {C} ^{3}}$, they are identical to those of the Bidodecateric heptacontadipeton.
