I'm hoping that this work might give me some valuable info on how to get started on various Project Euler[0] problems that I might otherwise have no idea how to approach, or that I wouldn't know what area of math to do research for.
This is exactly what I thought. In fact, when I got to the section that listed the right-truncatable primes, I immediately searched Euler because I knew there was a problem about them -- turns out I had already solved it though lol.
