In geometry the triaugmented dodecahedron is one of the Johnson solids J61 It can be seen as a dodecahedron with three pentagonal pyramids J2 attached to nonadjacent faces When pyramids are attached to a dodecahedron in other ways they may result in an augmented dodecahedron J58 a parabiaugmented dodecahedron J59 a metabiaugmented dodecahedron J60 or even a pentakis dodecahedron if the faces are made to be irregular Triaugmented dodecahedronTypeJohnsonJ60 J61 J62Faces3 2 6 triangles3 3 pentagonsEdges45Vertices23Vertex configuration2 3 53 3 2 6 32 52 3 35 Symmetry groupC3vDual polyhedron PropertiesconvexNetA Johnson solid is one of 92 strictly convex polyhedra that is composed of regular polygon faces but are not uniform polyhedra that is they are not Platonic solids Archimedean solids prisms or antiprisms They were named by Norman Johnson who first listed these polyhedra in 1966 1 External links editWeisstein Eric W Triaugmented dodecahedron Johnson Solid at MathWorld nbsp This polyhedron related article is a stub You can help Wikipedia by expanding it vte Johnson Norman W 1966 Convex polyhedra with regular faces Canadian Journal of Mathematics 18 169 200 doi 10 4153 cjm 1966 021 8 MR 0185507 Zbl 0132 14603 Retrieved from https en wikipedia org w index php title Triaugmented dodecahedron amp oldid 1093048524, wikipedia, wiki, book, books, library,
