Describe all nonisomorphic central extensions of Z_n by Z_2 x Z_2 meaning central group extensions of the following form
1 --> Z_n --> G --> Z_2 x Z_2 --> 1
Meaning, determine those nonisomorphic groups G that can be described by such an extension. Please also explain how you came up with the answer.

- Nonisomorphic Central Extensions - Describe all nonisomorphic central extensions of Z_2 x Z_2 by a cyclic group Z_n for arbitrary n, meaning central extensions of the form: 1 --> Z_n --> G --> Z_2 x Z_2 --> 1
- Isomorphism - Please provide a detailed solution to the attached problem. Prove directly that the map... is an isomorphism of ...with itself.
- Onto Homomorphisms - Please see the attached file for the fully formatted problems.
- Isomorphism - 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)
