The trirectified 421 polytope, also called the trirectified dischiliahecatonhexaconta-myriaheptachiliadiacosioctaconta-zetton, is a convex uniform 8-polytope. It has 240 birectified 321 polytopes, 2160 trirectified 7-cubes, and 17280 trirectified 7-simplices as facets. 4 birectified 321 polytopes, 5 trirectified 7-cubes, and 5 trirectified 7-simplices join at each tetrahedral-rectified pentachoric duoprismatic vertex. As the name suggests, it is the trirectification of the 421 polytope.
