In a previous article we examined some properties of knight-graphable words. A word is knight-graphable (NG) if the distinct letters of the alphabet used in the word can be placed on separate squares of an arbitrarily large chessboard such that a chess knight can spell out the word by starting on the square labelled with the word's first letter and making a series of knight's moves to the successive letters in the word.
