Summary

[edit]
Description Cet objet topologique peut s'obtenir en vrillant une bande de papier d'un demi-tour et en la collant sur elle-même. Cette bande n'a qu'une seule face (on peut parcourir l'ensemble de la surface sans franchir un bord) et qu'un seul bord (on peut parcourir tout le pourtour sans interruption).
