The medial hexacosichoron (Bower style acronym mix) is the regular compound of 120 pentachora, with full hexacosichoric symmetry. It can be considered as the 4-dimensional analogue of the compound of five tetrahedra. It can also be seen as a compound of 60 stellated decachora, and as a stellation of the hexacosachoron. The model has icosahedral symmetry.

A Zometool model has been constructed for the first time in 2020 (Paulo Freire)

Like the compound of 5 icositetrachora it is self-dual.

In the present vZome model, each teal ball connects six half-blue struts. Replacing these by a b1 and two b2's, bending over each other, cannot be done.
