In geometry, the parabiaugmented dodecahedron is one of the Johnson solids (). It can be seen as a dodecahedron with two pentagonal pyramids () attached to opposite faces. When pyramids are attached to a dodecahedron in other ways, they may result in an augmented dodecahedron (), a metabiaugmented dodecahedron (), a triaugmented dodecahedron (), or even a pentakis dodecahedron if the faces are made to be irregular. The dual of this solid is the Gyroelongated pentagonal bifrustum. External links Johnson solids
