    1. The problem statement, all variables and given/known data
    How to couple spin angular momenta of four electrons?

    2. The attempt at a solution
    I've no idea.
    I've learnt coupling of two angular momenta and Clebsch Gordan coefficient.
    But donno how to appy that to this system.

    Just do them two at a time, like regular addition. E.g. first add the spins of two electrons, then of the other two, then add those two resulting states together.
