Elongated pentagonal dipyramid

In geometry, the elongated pentagonal dipyramid is one of the Johnson solids (J₁₆). As the name suggests, it can be constructed by elongating a pentagonal dipyramid (J₁₃) by inserting a pentagonal prism between its congruent halves.

The 92 Johnson solids were named and described by Norman Johnson in 1966.
