For an alkane the number of possible constitutional isomers increases with increasing molecular size. The circle represents the six electrons which are delocalised between the six carbon atoms of the benzene ring. If the two rings that you want to fuse together are the same then you can skip Draw two six carbon rings that are fused together.
