Some of the mathematicians at the University of Bristol go to the pub on a Friday and the pub is sometimes revealed with a pubzle (a puzzle with a pub as the answer). I set three pubzles in 2023, can you solve them?

Some of the mathematicians at the University of Bristol go to the pub on a Friday and over the summer the pub is normally revealed with a pubzle (a puzzle with a pub as the answer) with a prize for the first person to solve the pubzle. I made three pubzles over the summer of 2022, can you solve them?

How do you keep track of your pint glasses in the office? How about etching one of your results on them?

How often do you get new words in crosswords? How many clues should you expect to get? What’s the longest clue? I recently downloaded over 7,000 Guardian cryptic crosswords to answer questions just like these.

Wordle has been taking the world by storm, but what is the best way to play? This blog post looks at a few different strategies and the optimum play for a few different versions of “best”

A couple of years ago I got fed up with looking at ads when doing something as simple as solving an anagram, so I decided to write my own solver.

This blog post quickly compares three different ways of enumerating the permutation graphs on \(n\) vertices. By using a canonical deletion approach, we can extend OEIS A123448 from \(n = 11\) to \(n = 14\).

There are 22576188846 unlabelled circle graphs on 13 vertices but how do we know that? This blog post looks at a few different ways of generating small circle graphs from the simplest ways up to a canonical deletion method.

A discussion about a potential title with my coauthors led to a question: What is the longest title for a maths paper?
