  While non-linear realizations of continuous symmetries feature derivative
interactions and have no potential, non-linear realizations of discrete
symmetries feature non-derivative interactions and have a highly suppressed
potential. These Goldstone bosons of discrete symmetries have a non-zero
potential, but the potential generated from quantum corrections is inherently
very highly suppressed. We explore various discrete symmetries and to what
extent the potential is suppressed for each of them.
