Angles for R.I. = 1.54
27 facets + 12 facets on girdle = 39
2-fold, mirror-image symmetry
L/W = 1.000 T/W = 0.267 T/L = 0.267
P/W = 0.435 C/W = 0.191
H/W = (P+C)/W+0.02 = 0.646
P/H = 0.673 C/H = 0.296
Vol./W^3 = 0.216
Addition # 4 - This is easy and fast to cut, it is a good design to cut if you have never done a checker top before. It is nice in almost any material, R.I. from 1.54 to 1.76 without changes. I prefer it in a smaller size, ½- 8cts…
