  12. I have a user that has a bad C code for generating
  13. graceful numbers. Does anyone have such a beast
  14. or a reference? I can't explain what a graceful
  15. number is, but it is evidently a mathematically
  16. accepted and defined beast. I can't find it in
  17. Numerical Recipes or some of Knuth's books though.
