Thank you to both of you for your help. Z_2=\left\{0,1\right\}, not \left\{0,1,2\right\}. Thank you for point that out! I was going from my lecture notes and I had written it down wrong. This makes the problem make a lot more sense.

Homework Statement I am suppose to determine if the following list of groups are isomorphic and if they are define an isomorphic function for them. a. [5Z, +],[12Z, +] where nZ = {nz | z\inZ} b. [Z6, +6]], [S6, \circ] c. [Z2, +2]], [S2, \circ] Homework Equations +6 means x +6] y = the...

Yes, that does appear to work! Thanks so much that never would have occurred to me.

1. Prove that for all boolean algebras if x+y=x+z and x'+y = x'+z then y=z. 2. Homework Equations : x+x' = 1, xx'=0, basically we are allowed to use the usual boolean algebra properties. 3.Attempt: This the second part of a problem, in the first part we had to give and example of...
