Lace

A lace is an informal term used to refer to any polytope formed by connecting other smaller polytopes.

Prisms are laces of two identical polytopes. Antiprisms are laces of a polytope and its dual. Pyramids are laces of a polytope and a point.

Most often, laces are used to refer to convex polytopes like segmentotopes, in which case the lace is given by a convex hull. However, the term can be applied to nonconvex polytopes as well, as long as the lace is formally specified.
