Rank of a group defined in such a way as to ensure subgroups have rank less than or equal to the whole group, which is automatically the case for dimensions of vector spaces, but not for groups such as affine groups. To distinguish these different definitions, one sometimes calls this rank the subgroup rank. Explicitly, the subgroup rank of a group "G" is the maximum of the ranks of its subgroups: Sometimes the subgroup rank is restricted to abelian subgroups. There is an algorithmic problem studied in group theory, known as the rank problem. The problem asks, for a particular class of finitely presented
