What’s Special About This Number?
I just found Shadow walkers the download.stetson.edu/~efriedma/numbers.html”>this site over on O’Reilly Radar. It lists the numbers 0 to 9999 and describes mathematical properties for that number. Here are the first few numbers to give you an idea of what is there:
<ol>
<li>
is the multiplicative identity.
<li>
is the only even prime.
<li>
is the number of spatial dimensions we live in.
<li>
is the smallest number of colors sufficient to color al planar maps.
<li>
5 is the number of Platonic solids.
<li>
is the smallest perfect number.
<li>
is the smallest number of faces of a regular polygon that is not constructible by
straightedge and compass.
<li>
is the largest cube in the Fibonacci sequence.
<li>
is the maximum number of cubes that are needed to sum to any positive integer.</li>
