3/24    Category: 8 letter words/phrases using only letters A-F.
        \_ fadedabe -abe
        \_ deadbabe, fadedabe -abe
        \_ The best I can get is defaced, but that's only 7.
        \_ egrep.  btw, using the stock freebsd dict/words, there are 11 6-
           letter words (includeing efface and deface) that meet the
           requirement, and 0 7- or 8-letter words.
                \_ Fabaceae?
        \_ cafebabe, deadbeef.  Is 0 allowed too?

             \_ b00bbabe
               \_ b00b1e5 !!!
               \_ b00bcafe, b00bfed, badb00b5, fabb00b, fee1b00b... </beavis>

           \_ Where do you get this dictionary?
              \_ http://wordlist.sourceforge.net
        \_ facefeed (fellatio).
        \_ cabba9e5
        \_ BADA55E5
           \_ Isn't the category A-F only?
