Infinite Set
A Set of 
elements is said to be infinite if the elements of a Proper Subset 
can be put into One-to-One correspondence with the elements of . An infinite set whose elements can be put into a One-to-One correspondence with the set of Integers is said to be CountablyInfinite; otherwise, it is called Uncountably Infinite.
