# What's the meaning of "totally antisymmetric" in Pauli's Principle?

 P: 70 Pauli's Principle says: "The wavefunction of two identical fermions must be totally antisymmetric". I know that, for a antisymmetric wavefunction, $(-1)^L*(-1)^{S+1}*(-1)^{I+1}=-1$ "totally antisymmetric" means this relation or it means that these 3 relations: $(-1)^L=-1$ and $(-1)^{S+1}=-1$ and $(-1)^{I+1}=-1$ must be verified simultaneously? Thank you!
