Torsion Generators of the Twist Subgroup

Abstract

We showed that the twist subgroup of the mapping class group of a closed connected nonorientable surface of genus $g\ge 13$ can be generated by two involutions and an element of order $g$ or $g-1$ depending on whether $g$ is odd or even respectively.
