Abstract: The linear congruent generators (LCG)arc widely applied to emulation and simulation. In this paper, we point out that the point set of 2-dimension, consisting of pseudo-random numbers gen-crated by LCG, alaways distributes over parallels of equal distance apart from each other. By using digital examples, we show that this defective geometrical structure might be improved distinctly by means of the combination.
