An inductive proof. I don\’t think you will find this one easier to understand.
My advice: Be patient and do inductions with clear examples.
________________
guess I can try to sketch out a proof based on mathematical induction if you cannot do that. Give me a few minutes.

Generalization is based on induction in special cases.
You can do it for general n cases by repeatedly doing what I have shown for n=4, by introducing Q’, Q”, Q”’, Q””, Q””’, Q”””’ until there are n of such rotation matrices. Personally, I don’t see any value in doing so except for introducing notational difficulty.
