报告摘要  Abstract

In the final lecture of the series I will consider permutation groups with the property that the semigroup generated by the group together with any non-permutation of fixed rank has the property that the non-units form an idempotent-generated semigroup. In the rank 2 case, this leads to an interesting conjecture for primitive permutation groups called the road closure conjecture. Related topics will also be considered if time permits.
