Abstract
This paper deals with , the six-particle contribution to the magnetic susceptibility of the square lattice Ising model. We have generated, modulo a prime, series coefficients for . The length of the series is sufficient to produce the corresponding Fuchsian linear differential equation (modulo a prime). We obtain the Fuchsian linear differential equation that annihilates the ‘depleted’ series . The factorization of the corresponding differential operator is performed using a method of factorization modulo a prime, introduced in a previous paper. The ‘depleted’ differential operator is shown to have a structure similar to the corresponding operator for . It splits into factors of smaller orders, with the left-most factor of order 6 being equivalent to the symmetric fifth power of the linear differential operator corresponding to the elliptic integral E. The right-most factor has a direct sum structure, and using series calculated modulo several primes, all the factors in the direct sum have been reconstructed in exact arithmetics.
