We experimentally observe the non-Abelian topological charges in a PT (parity and time-reversal) symmetric transmission line network. The quaternion-valued non-Abelian topological charges are clearly mapped onto the eigenstate-frame sphere. Meanwhile, we find a non-Abelian quotient relation which provides a global perspective to the distribution of edge/domain-wall states.
