Abstract
We study homeomorphisms and the homeomorphism groups of compact metric spaces using the automorphism groups of projective Fra\"iss\'e limits. In our applications, we investigate the Polish group of all homeomorphisms of the pseudoarc using the automorphism group of the pre-pseudoarc . Strengthening results from the literature, we show that the diagonal conjugacy action of on has a dense orbit. In our second application, we show that there exists a homeomorphism of that is not conjugate in to an element of .
