Angles for R.I. = 2.20
85 facets + 12 facets on girdle = 97
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.433 T/L = 0.433
P/W = 0.377 C/W = 0.241
H/W = (P+C)/W+0.02 = 0.639
P/H = 0.591 C/H = 0.378
Vol./W^3 = 0.274

Gram Book 1 - Be careful that the C4 facets are even, or the table will give you trouble. Other than that this design is fairly simple. The reflection is higher than it looks, 1-12cts.
