Abstract
We show that the group of homeomorphisms of the Cantor set has ample generics, that is, for every the diagonal conjugacy action of on has a comeager orbit. This answers a question of Kechris and Rosendal. We show that the generic tuple in can be taken to be the limit of a certain projective Fraisse family. We also present a proof of the existence of the generic homeomorphism of the Cantor set in the context of the projective Fraisse theory.
