Note: ~~ means an isomorphism exists. Moreover,if an isomorphism existed from G to G1 I would say G ~~ G1

Questions: If G is an infinite cyclic group, show that G ~~ Z (Z is the set of integers)

Solution Preview

G is an infinite cyclic group, then G=<a>, where a is a generator of G. Now we can define a map f from G to Z as follows:
for any b in G, b=a^i ...
