My fault. I meant because basis states are linearly independent functions, maybe they can always provide a basis for a representation of a given group.

Can we say instead that a wave function is a representation of an underlying group?

One of the most intuitive ways of deriving the transformations is the following. Consider an infinitesimal homogeneous Lorentz transformation ##\lambda = \delta + \epsilon K##. Put this into the Lorentz condition $$\Lambda_\mu{}^\sigma \eta_{\sigma \rho} \Lambda^\rho{}_\nu = \eta_{\mu \nu}...
