Wow, that's a deep question.
The answer has to do with the relationship between the reflection operator
and the rotation operator. Actually there are several possible answers:
1) In a world where rotation is a symmetry, you can pick a single
"standard" reflection (such as the one that takes X to -X) and then show
-- any odd number of reflections is equivalent to one standardreflection
plus a rotationThank you for your answer. Yes, I am familiar with the proof. But I was
-- any even number of reflections is equivalent to a rotation.
