Increased tridiminué icosahedron
The icosahedral tridiminué is a Polyèdre belonging to the solid of Johnson ( J 64). As the name indicates it, it can be built by decreasing a Icosaèdre three times over by detaching three pentagonal pyramids ( J 2) and by increasing it by attaching a Tétraèdre.
The 92 solid of Johnson were named and described by Norman Johnson in 1966.
