Abstract
The mutual gravitational potential between a pair of homogeneous polyhedra is expressed using an infinite series. The nested volume integrals are evaluated analytically and result in simple tensor expressions containing no special functions. However, complexity increases as O(6n), where n is the term degree. An alternate formulation due to Liebenthal is also presented.
