NAME
       prism - Prism reference element

DESCRIPTION
       The prism reference element is

	       K = { 0 < x < 1 and 0 < y < 1-x and -1 < z < 1 }

NUMBERING
       The  orientation  is  such that triedra (01, 02, 03) is direct and all faces, see from exterior, are in the direct sens.  References: P. L.
