replaced the word "rank" by "class number" and better picture + augmented question

| Dec 24, 2019 at 16:36 | comment | added | Geoff Robinson | What you are calling the rank is just the number of conjugacy classes, $k(G)$. | |
| Dec 24, 2019 at 13:39 | comment | added | Sebastien Palcoux | @YCor What is called "rank" here is not the usual one in group theory (i.e. smallest cardinality of a generating set for $G$) but the dimension of the Grothendieck ring of $Rep(G)$; this word has this sense in this framework. Of course these two notions are not equivalent. What word should be used in group theory? | |
| Dec 24, 2019 at 9:15 | comment | added | YCor | I'm not sure "rank" is the right word. For instance the groups $\mathrm{PSL}(2,q)$ are usually considered to have bounded rank, when $q$ varies. | |
