Parabiaugmented hexagonal prism
Template:Short description {{#invoke:Infobox|infobox}}Template:Template other
In geometry, the parabiaugmented hexagonal prism is one of the Johnson solids (Template:Math). As the name suggests, it can be constructed by doubly augmenting a hexagonal prism by attaching square pyramids (Template:Math) to two of its nonadjacent, parallel (opposite) equatorial faces. Attaching the pyramids to nonadjacent, nonparallel equatorial faces yields a metabiaugmented hexagonal prism (Template:Math). (The solid obtained by attaching pyramids to adjacent equatorial faces is not convex, and thus not a Johnson solid.)
