Trigyro-rhombicosidodécaèdre
The trigyro-rhombicosidodécaèdre is a Polyèdre which belongs to the solid of Johnson ( J 75).
As its name indicates it, it can be obtained starting from a rhombicosidodécaèdre to which one attached three pentagonal cupolas ( J 5) not-opposite turned to 36 degrees. The solids of Johnson connected are the Gyro-rhombicosidodécaèdre ( J 72) where a pentagonal cupola is turned, the Parabigyro-rhombicosidodécaèdre ( J 73) where two opposite pentagonal cupolas are turned and the Métabigyro-rhombicosidodécaèdre ( J 74) where two not-opposite pentagonal cupolas are turned.
The 92 solid of Johnson were named and described by Norman Johnson in 1966.
