The challenge is a take home team event that consists of a collection of interesting problems suggested by members of staff. These are challenging problems (some much more than others). You should feel proud if you can work out (part of) the solution to any of these problems. Above all, if you engage with the SoMaS challenge we want you to enjoy yourself! So, your submissions don't need to be close to complete; you are absolutely welcome to tell us anything you like about the problems that you felt were interesting or enjoyable! These observations can include, but are not restricted to, (partial) solutions, special cases, humorous remarks, and generalisations or variations of the problems. Every year, submissions delight, entertain and surprise us, and we hope that we can keep this good culture going.
