A simple model of an ordered stoichiometric alloy was considered. Computer simulations were used to determine the behavior of the tracer correlation factor and of the cosines of the angles between consecutive tracer jumps. The asymptotic behavior of the average of the cosine of the angle between jumps, for atoms which started from the wrong lattice, was derived analytically by considering vacancy jump sequences and was verified by computer simulation. The efficiency of the 6-jump cycle mechanism was also determined. It was shown that this mechanism rapidly became the predominant one as the lattice became more ordered.
