Angles for R.I. = 1.54
101 facets + 8 facets on girdle = 109
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.482 T/L = 0.482
P/W = 0.481 C/W = 0.175
H/W = (P+C)/W+0.02 = 0.676
P/H = 0.712 C/H = 0.259
Vol./W^3 = 0.251

Addition # 2 - This design can be hard to cut, you may have to cut the steps a couple of times to get them right. The spacing is critical, however, the rest of the cut is not very hard, 2-24cts. Cut in refractive indexes 1.54 to 2.14 (80.1%) with no changes.
