The factorial moments (FM) of multiplicity distributions in one- and two-dimensions are studied for Pb+Pb collisions at 158 AGeV/c. The results are compared with FRITIOF, RQMD and VENUS predictions. In the relation between FM and the number of partitions, M, obvious positive intermittence exponents, ϕq, are observed. The exponents, ϕq, are compared with the anomalous dimensions, dq. Then they are expressed in terms of Lévy stable indices, μ. Meanwhile the experimental data within the interval, 2<η<6, fulfills the requirements of the Lévy stable region (0 ≤ μ≤ 2), the results from the other intervals are away from this region. All their corresponding indices have negative values.
