Triaugmented dodecahedron
Template:Short description {{#invoke:Infobox|infobox}}Template:Template other
In geometry, the triaugmented dodecahedron is one of the Johnson solids (Template:Math). It can be seen as a dodecahedron with three pentagonal pyramids (Template:Math) attached to nonadjacent faces. When pyramids are attached to a dodecahedron in other ways, they may result in an augmented dodecahedron (Template:Math), a parabiaugmented dodecahedron (Template:Math), a metabiaugmented dodecahedron (Template:Math), or even a pentakis dodecahedron if the faces are made to be irregular.
