EXAMPLE
|
If n=62 then the number of benzenoids with 22 hexagons with C_(2h) symmetry is 2.
If n=64 then the number of benzenoids with 22 hexagons with C_(2h) symmetry is 32.
If n=66 then the number of benzenoids with 22 hexagons with C_(2h) symmetry is 138.
If n=68 then the number of benzenoids with 22 hexagons with C_(2h) symmetry is 510.
If n=90 then the number of benzenoids with 22 hexagons with C_(2h) symmetry is 232842.
