;Definition
For the purposes of this task a '''hex word''' means a word which (in lower case form) consists entirely of the letters '''a, b, c, d, e''' and '''f'''.
Line 6:
Using [http://wiki.puzzlers.org/pub/wordlists/unixdict.txt unixdict.txt], find all hex words with '''4''' letters or more.
 
Convert each such word to its decimal equivalent and compute its base 10 [[Digital_root|digital root]].
 
Display all three in increasing order of digital root and show the total count of such words.
 
AlsoKeeping filter out all suchonly words which contain at least '''4''' distinct letters and, display the same statistics but in decreasing order of decimal equivalent together with their total count.
