A book of mathematical tables will contain listings for some of the functions listed in this Demonstration. For example, tables of square numbers and cube numbers are included. If you are curious to find out more about a particular sequence, put a list of the first few terms into the The On-Line Encyclopedia of Integer Sequences, or take a look at the corresponding Wolfram MathWorld link. If the numbers are too large for the available space, use the "larger numbers" option, or decrease the number of columns.
