A novel efficient computer‐oriented approach, based on the DAST (dualist angle‐restricted spanning tree) code, is introduced for enumeration and generation of planar polyhex hydrocarbons. It is much faster than other approaches in the literature. The numbers of planar polyhex hydrocarbons with 14 hexagons are reported for the first time.

An algorithm is developed for enumerating all 2-factors of polyhexes. Some properties of 2-factors of polyhexes are discussed.
The enumeration of polyhexes can be easily carried out by utilizing a compact name (CN) approach to code chemical structures. The Fortran program performing generation of benzenoid hydrocarbons with 1-10 rings is presented. The computed structures are divided into various classes according to their
## Abstract A computer‐oriented algorithm is developed for enumerating and generating all rigorously planar benzenoid hydrocarbons. An additional algorithm is also developed for identification and enumeration of carcinogenic bay regions. The results are reported for undisrupted benzenoid structures
The enumeration of benzenoids is studied with the aid of different modifications of a computer program. Known values for the number of cata-condensed and of all benzenoids with h (number of hexagons) up to eight are reproduced. These benzenoids are classified into (a) unbranched of different symmetr
