Elliptic Curves  --  Galois Field Arithmetic

<P>
Find out about the wonderful world of GF[2^K], where 2=0, plus is minus,
and squaring is a linear operator.  And why they are called elliptic curves. <P>

Multiperfect Numbers  --  Multiply Perfect Numbers  --  Pluperfect Numbers  --  MPFNs

<P> This list is a couple of years out of date.  There's been a lot of
activity lately.  There are now about 3000 known MPFNs.
