  Inspired by a possible relation between large $N$ gauge theory and string
theory, we search for nontrivial fixed points in large $N$ gauge theory in more
than four dimensions. We study large $N$ gauge theory through Monte Carlo
simulation of the twisted Eguchi-Kawai model in six dimensions as well as in
four dimensions. The phase diagram of the system with the two coupling
constants which correspond to the standard plaquette action and the adjoint
term has been explored.
