Abstract
For a nite group G the commutativity degree denote by d(G) and de nd:
$$d(G) =\frac{|\{(x; y)|x, y\in G,xy = yx\}|}{|G|^2}.$$
In [2] authors found commutativity degree for some groups,in this paper we nd commutativity degree for a class of groups that have high nilpontencies.
Keywords
Presentation of groups; Finite groups; commutativity degree
