Theorem
Let $T = \struct {S, \tau}$ be a topological space which is ultraconnected.
Then $T$ is connected.
Proof
Let $T = \struct {S, \tau}$ be a topological space which is ultraconnected.
From Ultraconnected Space is Path-Connected, $T$ is path-connected.
The result follows from Path-Connected Space is Connected.
