Analytic expressions for the cutting line number μ of a single-wall carbon nanotube (SWNT) which gives van Hove singularities for optical transitions are found to exist around μ=N 3 for most SWNTs, where N is the number of cutting lines of the SWNT. However, for metal-2 SWNTs, the cutting line number shows an irregular dependence on (n,m). In this paper a classification is proposed for metal-2 nanotubes which are classified as either metal-2p or metal-2m SWNTs. The appearance of metal-1, metal-2p, and metal-2m SWNTs in a two-dimensional (n,m) plot is not regular.
