## Exchanges of the intervals and minimal sequences. (Echanges de trois intervalles et suites minimales.)(French)Zbl 0902.68153

Summary: This work is a study of minimal sequences generated by exchanges of three intervals. We employ the notion of “word graph”. The main result is that the evolution of “$$n$$-segements” is completely defined by 62 substitutions acting on alphabets of 3 or 4 letters.
