Recall that a matching in G is a sub graph with all vertices of degree 1 and that a perfect matching is a sub graph with all vertices of degree 1 that includes all vertices of G.

(a) Find as many different perfect matchings as you can in a 6-cycle graph.

(b) Find as many different perfect matchings as you can in K_4.

(d) How does the concept of perfect matchings relate to edge coloring of k-regular graphs?
