Abstract
The symmetry group of the staggered fermion transfer matrix in a spatial direction is constructed at finite temperature. Hadron-like operators carrying irreducible representations of this group are written down from the breaking of the zero temperature group. Analysis of the correlators in free field theory suggests new measurements which can test current interpretations.
