ABSTRACT
The article discusses the related subject in mathematics that deals with the study on group number function. It presents a series of theorems and corollaries with the corresponding proofs that help explain the properties of the group number function. Moreover, it presents a set of examples, graphs, tables and scholarly discussions that support the detailed account of the history of the study.

Any group G gives rise to a 2-group of inner automorphisms, INN(G). It is an old result by Segal that the nerve of this is the universal Gbundle. We discuss that, similarly, for every 2-group G(2) there is a 3-group INN(G(2)) and a slightly smaller 3-group INN0(G(2)) of inner automorphisms. We...
