You can find some ideas for what might constitute a “toy project” here.
The Lean 4 project containing the Lean files for the lectures is here.
The module is based on the proof assistant Lean 4. We will use Mathlib, the mathematical library of Lean 4.
You can find ways to interact with Lean and Mathlib on the Mathlib webpage.
Note: Lean 3 vs Lean 4
Lean 4 is the latest version of Lean.
Switching from Lean 3 to Lean 4 means rewriting all the code, all the supporting information and all the webpages.
This process is completed for Mathlib, however there are still online resources that talk about Lean and mean Lean 3.
In this module, we will only work with Lean 4.
