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?

    Start by writing out the DEFINITION of "same number"!
