Homework Help: Infinite sets.

  1. Apr 20, 2005 #1
    Show that they are the same number of points in a line, in a plane and in the space.
    I have one more question: Which set has a cardinal number greater than the continuum. Why?

    Thanks in advance.

    Sounds like homework. Have you had any thoughts on it? Know any useful facts about cardinality?
