Towards Efficient Normalizers of Primitive Groups

Sergio Siccha

We present the ideas behind an algorithm to compute normalizers of primitive groups with non-regular socle in polynomial time. We highlight a concept we developed called permutatio…

Normalisers of primitive permutation groups in quasipolynomial time

Colva Roney-Dougal, Sergio Siccha

We show that given generators for subgroups $G$ and $H$ of $S_{n}$ , if $G$ is primitive then generators for $N_{H} (G)$ may be computed in quasipolynomial time, namely…
