1. normal subgroups

I have the stack with the following problem:

Let X=wedge sum of n-circles. show that the normal subgroup of pi_1(X) is having a caylay graphs of two generators.

I tried to see what happen in case of n=2, but I don't know how to show it in that case either, can anyone give me a hint to start with?

Glad to hear you're using this: I plan to keep it much more aggressively up-to-date than has been the case in the past, but don't hesitate to let me know if you find errors or need clarifications.
