Metabiaugmented hexagonal prism
Template:Short description Script error: No such module "Infobox".Template:Template other
In geometry, the metabiaugmented hexagonal prism is one of the Johnson solids (J56Script error: No such module "Check for unknown parameters".). As the name suggests, it can be constructed by doubly augmenting a hexagonal prism by attaching square pyramids (J1Script error: No such module "Check for unknown parameters".) to two of its nonadjacent, nonparallel equatorial faces. Attaching the pyramids to opposite equatorial faces yields a parabiaugmented hexagonal prism. (The solid obtained by attaching pyramids to adjacent equatorial faces is not convex, and thus not a Johnson solid.)
