# 3rd SYGN Workshop

Last week I was at the 3rd Symmetries of Graphs and Networks Worskhop and PhD Summer School in Discrete Mathematics at Rogla, Slovenia. The SYGN meeting has been held every two years with the first being at Banff in 2008 and this was the second one held at Rogla. The summer school part continues on the tradition started last year.

Once again the Slovenians did a great job at organising it and it was a very enjoyable conference. I was invited to give a minicourse as part of the summer school on The Polycirculant Conjecture. I have touched on this previously. Boštjan Kuzman kindly took latex notes of my lectures and these are available at the conference webpage together with the slides from the other courses and talks from the workshop. The other courses were on Graph enumeration by Stephan Wagner and Finite geometries by György Kiss.

Four talks that I found particularly interesting were:

- Roman Nedela’s survey on regular maps. This gave a great overview of the area and I learned a lot about what the main problems in the area are.
- Jozef Siran’s survey on the degree-diameter problem.
- Joy Morris’s talk on the structure of circulant graphs.
- Steve Wilson’s talk on Tales from the census. This is his census with Primož Potočnik on 4-valent edge-transitive graphs.
