The square antiprismtwisted square antiprism ratio in LnDOTAtetraamide chelates is a critical parameter in governing waterexchange kinetics and ultimately the utility of a chelate as a PARACEST MRI contrast agent.Twisted Antiprism. A twisted antiprism is obtained from an antiprism by rotating its top face by or; it has a nontrivial infinitesimal isometric deformation. The case of the twisted triangular antiprism is known as Wunderlich's (or Schoenhardt's) octahedron. According to the BlaschkeLiebmann theorem, four nonadjacent faces twisted square antiprism

Twisted prism. A twisted prism is a nonconvex prism polyhedron constructed by a uniform qprism with the side faces bisected on the square diagonal, and twisting the top, usually by q radians (180q degrees) in the same direction, causing side triangles to be concave.

In geometry, the square antiprism is the second in an infinite set of antiprisms formed by an evennumbered sequence of triangle sides closed by two polygon caps. It is also known as an anticube. It is also known as an anticube.**twisted square antiprism** The geometrical definition of an antiprism is a polyhedron composed of two parallel copies of some particular polygon, connected by an alternating band of triangles. Here I present a twist square antiprism box. In the first photo the colorchanged box is folded insideout.
