The next-smallest infinite set is all points on a line {power of the continuum} {aleph one}, which is equivalent to all n-dimensional space points and to all real numbers. The second-smallest infinite set is all curves {aleph two}. Even-higher infinite sets exist, up to infinity {aleph infinity} {aleph naught naught}.
