■DE群多面体の計量(その73)
Wythoff's constructon for uniform polytopes, p49の局所幾何の計算.
(1,15,60,80,45,12,1)
大域幾何は
(432,3240,7920,7200,2430,342)
===================================
もしファセットが3種類だとしたらhγ5(頂点数16),α5(頂点数6)のほかに,もう1種類(頂点数80).
f5=(x/16+y/6+z/80)・f0
x/16+y/6+z/80=342/432
270x+720y+54z=3420
x+y+z=12
720x+720y+720z=8640
450x+666z=5220 (NG)
