My quantum information lecture notes state that neither $H$ nor $T$ is a rotation of (irrational * $\pi$).

However it states that both $TH$ and $HT$ are.

Could somebody explain why?

    Without writing out all the math, consider this analogy: when you move one km north, and then one km east, you have moved $\sqrt{2}$ km northeast, which is an 'irrational distance' – JSdJ May 30 '22 at 15:19
