In Baym's Lectures on Quantum Mechanics he derives the following formula(adsbygoogle = window.adsbygoogle || []).push({});

[n.L,L]=ih L x n

(Where n is a unit vector)

I follow everything until this line:

ih(r x (p x n)) + ih((r x n) x p) = ih (r x p) x n

I can't seem to get this to work out. What properties is he using here?
