96 index
L/W = 1.000
P/W = 0.470 C/W = 0.470
H/W = (P+C)/W+0.02 = 0.959
P/H = 0.490 C/H = 0.490
Vol./W^3 = 0.431

Addition # 14 – Another set of star facets can be placed at C5, P5 on a large bead. This is fast and easy to cut and works well in about any material. Tables can be cut, if desired, on both top and bottom.
