2-fold, mirror-image symmetry
96 index L/W = 1.246 T/W = 0.840
T/L = 0.674 P/W = 0.383 C/W = 0.130
H/W = (P+C)/W+0.02 = 0.532
P/H = 0.719 C/H = 0.243
Vol./W^3 = 0.179
Addition # 7 - Basically cut this like a square, then cut the P3(G) to get the L/W… This is easy and fast. I like it in about any material, it works well in dark colors. Cut in refractive indexes 1.54 to 1.93 with no changes. This design makes nice earrings…
