  We consider the large N limit of four dimensional SU(N) Yang-Mills field
coupled to adjoint fermions on a single site lattice. We use perturbative
techniques to show that the Z^4_N center-symmetries are broken with naive
fermions but they are not broken with overlap fermions. We use numerical
techniques to support this result. Furthermore, we present evidence for a
non-zero chiral condensate for one and two Majorana flavors at one value of the
lattice gauge coupling.
