The deficiency of a finite presentation is the number of generators minus the number of relators. We say a group is large if it has a finite index subgroup which surjects onto the non-abelian free group of rank 2.

There are several results in the literature linking deficiency and largeness. We will go over some of these results and see how a modification of deficiency may be used to study the largeness of presentations which have proper power relators.
