A pangram is a set of words in which each letter of the alphabet appears exactly once. Various people, including such distinguished mathematicians as the English logician Augustus De Morgan and the American information theorist Claude Shannon, have searched for pangrams that can be arranged in a meaningful sentence, but all efforts have required extensive explanations of the message the sentence is attempting to convey. In view of these difficulties, it seems prudent to abandon this additional requirement, regarding a pangram as a list of words and nothing more.
