As a common term for commutation and permutation we choose ‘mutation’. […] we define mutation as a function existing between first-degree derivates of one and the same class, a function that has relation to a function between other first-degree derivates of one and the same class and belonging to the same rank. - Hjelmslev (1961), a pag.73-74
