Hey everyone, hope you're having a great day. ↵
Here's a question about the famous ![post correspondence problem](https://en.wikipedia.org/wiki/Post_correspondence_problem)↵
This problem is undecidable according to Wiki Pedia, which means there are no algorithms to solve the problem. but can't we simply try all possible permutations of the dominos? what am I misunderstanding?
