Homework Statement
Show ZXZ is an infinite cyclic group. Under addition of course.
Homework Equations
The Attempt at a Solution
So this obviously is an infinite cyclic group. Z is generated by <1> or <-1>.
The problem I run into here is I think <(1,1)> will only generate elements of the form (a,a) s.t. a is an element of Z, (think along the diagonal). I do not see a way to generate something like (2,3).
