Note: "medial" section is f3/2x3x, which is a faceting of x3v3a, where a = v² = 2x-f. In fact the "diagonals" of v3a have size x and 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 f . x (underneath the x . a), to f3/2x . (faceting of x3v . in turn), and . x3x (deep underneath . v3a – and thus directly underneath the opposite x3v).

Incidence matrix according to Dynkin symbol

reduced( ofx3/2oxx3xxx&#xt by 4x {6/2} )   → height(1,2) = sqrt[3+sqrt(5)]/4 = 0.572061
