# Covering spaces for $S^1 \vee S^1\vee S^1$

When I read the HATCHER book(algebraic topolog) a question i found on a pdf and the truth is i cant find a way to solve it and realize it! the question which i saw after reading page 57/58/59( covering spaces of HATCHER) is:

> How could we find the covering space corresponding to $$N=N()$$ for $$S^1\vee S^1 \vee S^1$$

Obviously the graph of $$S^1\vee S^1 \vee S^1$$ hast three orbitation and one vertex and 3 edges.

I read the HATCHER and i realize how he identified orbitations and explains covering spaces for $$S^1\vee S^1$$ ,but there isn't and guidness for $$S^1\vee S^1 \vee S^1$$ and the way to show covering spaces corresponding to i.e $$N$$ (converse situation explained in HATCHER)

If someone could help me to realize the way of proof and solution i would be so much grateful.
