In geometry, the elongated pentagonal dipyramid is one of the Johnson solids ("J"16). As the name suggests, it can be constructed by elongating a pentagonal dipyramid ("J"13) by inserting a pentagonal prism between its congruent halves.
The 92 Johnson solids were named and described by Norman Johnson in 1966.
