Fig. 3: Comparisons of the search space for all homotops (blue) and the subspace for symmetric homotops (orange).

The number of homotops are plotted in logarithmic scale w.r.t. a the composition of a TOh260 binary NA and b the number of atoms in the NA. The green and red curves in the inset of (a) shows the number of symmetric homotops with threefold and fourfold mirror circular symmetry, respectively.
