Abstract: It is shown that for a large class of spaces, almost all the homeomorphisms of the space do not satisfy the Poincaré Recurrence Theorem. More specifically, let $ X$ be a compact manifold with a nonzero Euler characteristic and $ H(X)$ be the space of all homeomorphisms of $ X$ onto $ X$. $ H(X)$ is given the compact open topology. Then the set of all the homeomorphisms of $ X$ which satisfy the Poincaré Recurrence Theorem is nowhere dense in $ H(X)$.
