EXAMPLE
| If n=66 then the number of polyhexes with 24 hexagons with D_(2h) symmetry is 1.
If n=68 then the number of polyhexes with 24 hexagons with D_(2h) symmetry is 2.
If n=70 then the number of polyhexes with 24 hexagons with D_(2h) symmetry is 2.
If n=72 then the number of polyhexes with 24 hexagons with D_(2h) symmetry is 7.
