摘要：

A complete generation and enumeration of helicenes through fifteen hexagons was executed. The systems are classified according to neo (normal/essentially disconnected/non-Kekulean), the color excess (Delta values), and the CnHs isomers. Furthermore, the ''soft'' and ''hard'' helicenes are distinguished. The method of combinatorial constructions (without use of computers) is demonstrated for some classes of helicenes with ten hexagons.
