Abstract
We construct the general formula for a set of discrete gauge states
(DGS) in c < 1 Liouville theory. This formula reproduces the
previously found c = 1 DGS in the appropriate limiting case. We also
demonstrate the SO(2,C) invariant structure of these DGS in the old
covariant quantization of the theory. This is in analogy to the
SO(2,C) invariant ring structure of BRST cohomology of the theory.
