Abstract
States of the Gutzwiller-projected free Fermi gas comprise exact eigenstates of the t-J model describing mobile vacancies in the infinite-range spin-1/2 Heisenberg antiferromagnet. We discuss the nature of these eigenstates together with their corresponding energies at all interaction strengths and hole densities.
