Another achiral carbon nanotorus: C200

A smaller beaded toroids with 300 beads. This corresponds to nanotorus with 200 carbon atoms. Note that this molecule and all previous molecules have exactly 10 heptagons located periodically in the inner rim and 10 pentagons in the outer rims.

Since the beads are in fact chemical bonds in the molecule, and each carbon has three CC bonds, we have the simple rule for calculating the relation between the number of beads and the numbers of carbons:

the number of carbons = the number of beads *3 /2
