Helical substructures of 4D constructions that determine the structure of α-helices
{{output}}
In a 4D polytope {3, 3, 5}, a 40-vertex toroidal helix is selected that unites the vertices of two orbits of the axis 20/9 with the angle of rotation 9 × 360°/20 = 162°. Symmetrization of this helix allows one to select in the 3D spherical space a helix {40... ...
