Fr. Magnus Wenninger
(I am submitting this in connection with the invited paper session commemorating Fr. Magnus.)
Fr. Magnus Wenninger O. S. B. (1919 - 2017) created many wonderful
polyhedral models. This one shows five colored cubes whose
vertices are also the vertices of a regular dodecahedron. Each of
these cubes shares 24 symmetries with the dodecahedron. These form
the five conjugate subgroups isomorphic to A_4xZ_2 in the entire
There will be an invited paper session Friday afternoon called "Polyhedra, Commemerating Magnus J. Wenninger." His work spurred a resurgence of interest in polyhedral geometry.
