# About the Solutions to Catriona Agg's Puzzles The purpose of these pages is to create a list of solutions to Catriona Agg's puzzles and index which techniques are used. One use of this would be to determine which puzzles could be used to develop a deeper understanding of those techniques. Each puzzle has three pages: a main page, a solution page, and a techniques page. The main page has the puzzle together with details of where it has appeared in social media. The main page does not contain any spoilers about the puzzle's solution. The techniques page lists the (main) techniques used in a solution. Where multiple solutions are given, these are listed separately on that page. Then the solution page contains one or more solutions with links to the ideas and techniques used. The puzzles were originally announced on twitter, and considerable discussion ensued. When I originally created this wiki then it was still acceptable to link directly to twitter. I no longer consider that to be the case so while I will provide enough information that you could find the original twitter posts then I am in the process of removing the direct links. Some puzzles have been reposted on BlueSky and I am adding direct links to those. For the time being, this wiki is locked. However, it is always useful to have feedback so there is a [github project](https://github.com/loopspace/Mathforge-Notes) to track suggestions and errors.
