Increased triangular prism
The triangular prism increased is a geometrical Figure belonging to the solid of Johnson ( J 49). As the name indicates it, it can be built by increasing a triangular prism by attaching a square Pyramide ( J 1) to one of its equatorial faces. The resulting solid reveals a surface resemblance to the triangular Gyrobiprisme ( J 26), the difference being that in this last a second triangular prism is attached rather than a square pyramid.
The 92 solid of Johnson were named and described by Norman Johnson in 1966.
