The global symmetry generated by K_n is a subgroup of the stringy gaugesymmetry. We explore the part of the vacuum manifold related by this symmetry.A strong evidence is presented that the analytic classical solutions to thecubic string field theory found earlier in Refs. [5,6] are actually related bythe symmetry and, therefore, all of them describe the same tachyon vacuum. Someremaining subtlety is pointed out.Comment: 28 pages; v2: errors and typos correcte
