Computational Algebra Seminar: Voight -- M23 is a Galois group over the rationals

We celebrate a breakthrough Magma calculation by Xiaoyu Huang, Blake Jackson, Kyu-Hwan
Lee, Bjorn Poonen, Rachel Pries, and Shaowu Zhang proving that the Mathieu group M_23
has a regular realization as a Galois group over the rationals.
