| To gain orientation, it is first shown that the critical exponents of the Gaussian model (GM) are embraced by the AdS/CFT model of Iqbal, Liu and Mezei (2012) [1] (ILM below). While the GM exponents involve solely the dimensionality d, we then demonstrate how the universality class n can also be included via ILM model in the case of sufficiently large n. These latter results can be viewed as approximate summations of the epsilon expansion to all orders for sufficiently large n. For the three exponents beta, nu and eta the range of validity may be wider in the variable n. However, the exponent gamma is always unity in the ILM model, independently of the choice of n and d. Generalizations of the ILM string theory model should therefore be sought. Furthermore, this Letter discusses the critical exponents expressed in terms of both the dimensionality d and the universality class n, and specially, some formulae for large n limit have been given.
