The system is right!

The Cayley graph (and its diameter) depends not only of the group but also on a set of generators, and a group can have more than one sets of generators. For example, if you take the integers modulo 6 with the addition, then both {1} and {2,3} are sets of generators, with different Cayley graphs.

The method .gens() choses a particular set of generators. In the .cayley_graph() method, you can change this arbitrary choice by setting your own set of generators.

For example, if you take consider the group of integers modulo 6 with (with the addition, addition), then both {1} and {2,3} are sets of generators, with different Cayley graphs.

For example, if you consider the group of integers modulo 6 (with the addition), then both {1} and {2,3} are sets of generators, with leading to different Cayley graphs.
