     Those of you who remember the net kook SOLLOG, may remember his
     claim to have solved the primality testing problem.
 
     His algorithm was: check for divisibility by 2, then 3, then 5,
     then 7, then 11; check if the number is a perfect square; then apply a
     secret rule he would not divulge.
 
     I was amused that he got all the way out to 11 before realizing that
     he would have to change tack.
