CHEMICAL FORMULAS OF SINGLE CORONOIDS

Parts of this chapter, like the preceding chapter, is a specialization of relations from Chapt. 3 for s 1, but also other aspects are treated. In particular, a condse treatise of the processes referred to as drcumscribing and excising is offered. These processes are espedally important when it comes to extremal polyhexes the extremal single coronoids is another main subject of this chapter. All the treatments in this chapter are (more or less) oriented towards expressions in terms of the coefficients of the formulas, viz. n and a, as is reflected in the title. 

It is recalled (cf. Par. 3.7.1) that a (chemical) formula for a y-polyhex can be written (n s). Then one has for single coronoids  

Let the set of p polyhexes which are compatible with the formtila be identified by 

Here isomer is used in a restricted sense according to the definition of this term in Par. 3.6.1. 

The above formalism is also applicable to benzenoids, B B indicates that B
