I know that every nonempty Hausdorff compact space with no isolated points is uncountable, so I was wondering if we could substitute the nonempty Hausdorff part with it being infinite.
Is every infinite compact space with no isolated points uncountable

Best Answer
No. For instance, you could take a countably infinite set with the indiscrete topology.
You could consider that example to be cheating, as its $T_0$ quotient does have isolated points (so the space has points which are "isolated" from all points that they are topologically distinguishable from at all). For an example which is additionally $T_0$ (even $T_1$), you could take a countably infinite set with the cofinite topology.
