Non-Trivial Discrete Space is not Irreducible

Corollary to Non-Trivial Discrete Space is not Connected

Let $T = \left({S, \tau}\right)$ be a non-trivial discrete topological space.

$T$ is not irreducible.

Proof

Aiming for a contradiction, suppose $T$ is irreducible.

From Irreducible Space is Connected, we have that $T$ is connected.

But this directly contradicts Non-Trivial Discrete Space is not Connected.

The result follows from Proof by Contradiction.
