Note: "medial" section is f3/2x3o, which is a faceting of x3v3o. In fact the "diagonals" of x3v have size f. From this line set of edges and those inscriptions only those of size x and f are taken, then giving rise to faceting faces f3/2x . (faceting of x3v . in turn), and . x3o (underneath . v3o).

Incidence matrix according to Dynkin symbol

reduced( ofx3/2oxx3ooo&#xt by 2tet )   → height(1,2) = sqrt[3+sqrt(5)]/4 = 0.572061
