### The QPA software

I am involved in developing software for carrying out computations for finite dimensional quotients of path algebras over the fields that are available in GAP, which is the programming language used to program QPA (see www.gap-system.org). For those of you who want to try out this software I will below include instructional videos for how to install and use this software. In particular, how you can use it to do some of the problems on the problem sheets.
