N2 - The √∈-expansions for critical exponents of the weakly disordered Ising model are calculated up to the five-loop order and found to possess coefficients with irregular signs and values. The estimate nc = 2.855 for the marginal spin dimensionality of the cubic model is obtained by the Padé-Borel resummation of the corresponding five-loop e-expansion.
