Dihedral angles
• at {6} between hip and toe:   arccos(-sqrt[9+3 sqrt(5)]/4) = 172.238756°
• at {4} between dip and hip:   arccos(-sqrt[(10+2 sqrt(5))/15]) = 169.187683°
• at {4} between dip and toe:   arccos(-sqrt[(5+2 sqrt(5))/10]) = 166.717474°
• at {10} between dip and grid:   162°
• at {4} between grid and hip:   arccos(-sqrt[(3+sqrt(5))/6]) = 159.094843°
• at {6} between grid and toe:   arccos(-sqrt[7+3 sqrt(5)]/4) = 157.761244°

As abstract polytope gidpixhi is isomorphic to gaquidapixhi, thereby replacing the decagons by decagrams, resp. replacing the grid by gaquatid and the dip by stiddip.
