EXAMPLE
|
If n=62 then the number of benzenoids with 22 hexagons with D_(2h) symmetry is 1.
If n=64 then the number of benzenoids with 22 hexagons with D_(2h) symmetry is 3.
If n=66 then the number of benzenoids with 22 hexagons with D_(2h) symmetry is 3.
If n=68 then the number of benzenoids with 22 hexagons with D_(2h) symmetry is 6.
If n=90 then the number of benzenoids with 22 hexagons with D_(2h) symmetry is 81.
