Is every isomorphism between groups preserves cardinality of elements?

[QUOTE="Mr Davis 97, post: 6020666, member: 515461"] I'm just confused about how the two statement are saying the same thing. Basically what I am trying to do is to put the statement into prenex normal form and then to interpret how the statements are equivalent. I'm using the rule for taking the quantifier of the consequent that is described here: [URL]https://en.wikipedia.org/wiki/Prenex_normal_form#Implication[/URL] Edit: Actually, I used the wrong rule to begin with, so in this case my question is meaningless. If I come across another example I'll ask. [/QUOTE]
