Squares, cubes, and tesseracts are kurkubli be li ny. Tilted squares, octahedra, etc. might be called dutkurkubli be li ny; they are the duals of their respective kurkubli. La'edi'u are the only regular kubli be li su'o 5. The others in 3d are the icosahedron and dodecahedron; in 4d there are a solid with (IIRR) 120 tetrahedral faces which meet 20 at a corner, a solid with dodecahedral faces which meet four at a corner (dual of the preceding), and one with 24 octahedral faces, which is its own dual. Then there are cuboctahedra, rhombic dodecahedra (dual of CO), and assorted other semiregular polyhedra. phma
