This complex polyhedral lace prism has mutually dual complex polygons for bases. Accordingly the lacing faces here simply are pyramids only: vertex atop center of 3-edge. Each base had used a hex as their real space embeddings. Thus the here to be used embedding happens to result in the according alterprism.
