hexadecachoron (plural hexadecachorons or hexadecachora)
 (mathematics) A fourdimensional object equivalent to an octahedron, constructed out of sixteen tetrahedra.
 2005, V H Satheesh Kumar and P K Suresh, Are We Living in a Higher Dimensional Universe?, page 3:
 In a world with four spatial dimensions, for example, we can construct only six regular solids, viz pentatope, tesseract, hexadecachoron, icositetrachoron, hecatonicosachoron and hexacosichoron.
 2009, P. Khavari and C. C. Dyer, Aspects of Causality in Parallelisable Implicit Evolution Scheme, page 7:
 We have chosen the surfaces of a pentatope (5cell) as well as a hexadecachoron (16cell), which are simple standard triangulations of a 3sphere, shown in figure (7), as our underlying lattices.
 2011, Jin Akiyama and Ikuro Sato, The element number of the convex regular polytopes, page 271:
 In four dimensions, surprisingly, there are three spacefilling convex regular polychora: the tesseract (the hypercube in ℝ^{4}), the hexadecachoron, and the icositetrachoron.
