More on the 3p paper
I wrote here about Peter Neumann’s paper on primitive permutation groups of degree 3p, where p is a prime number. Well, summer is almost over, but my undergraduate research intern Marina AnagnostopoulouMerkouri and I have done our work and produced … Continue reading
Peter Neumann’s 3p paper
In 1955, Helmut Wielandt published a paper proving the following theorem: Let G be a primitive permutation group of degree 2p, where p is a prime greater than 3, which is not doubly transitive. Then p = 2a2+2a+1 for some positive integer … Continue reading
Peter Neumann memorial meeting
On Saturday, I was in Oxford for a memorial meeting for Peter Neumann, organised by Chris Hollings for the British Society for the History of Mathematics (of which Peter was a past president). It was a hybrid meeting, with half … Continue reading

The coincidence of Peter Neumann’s funeral and Eric Lander’s elevation in the last few days has inevitably made me think about family (in the mathematical sense). First, pictures of my aunts and uncles, brothers and sisters, sons and daughters, taken … Continue reading

Charles Sims
This morning I received the news that Charles Sims died on Monday. Sims was one of the most influential figures in computational group theory, but was much more besides. His name is attached to two sporadic simple groups; the one … Continue reading
Beginning a career
Yesterday was my tenth consecutive day of conferences. I’ll start this post with a detour. Bill Tutte was one of the deepest thinkers on combinatorics in the twentieth century. One of my favourite mathematics books is his Graph theory as … Continue reading
