Dome which results from the stacking of pentagons, all but one which are of equal size. Each of the resulting pentagons is subdivided into six triangles, with a single vertex in the center. This assembly can be constructed with rectangular section struts or with circular section tubular struts and vertex joints (hubs).

A variation of the vertex joints was developed called Vortexial Vertexes (1952), which proposed five metal sockets hinged to each other following the pentagonal configuration, from which the struts can radiate.

This case can result in even, non-oriented, and continuous enclosures.
