Query: Renormalized sextic coupling constant for the two-dimensional Ising
  model from field theory   The field-theoretical renormalization group approach is used to estimate the
universal critical value g_6^* of renormalized sextic coupling constant for the
two-dimensional Ising model. Four-loop perturbative expansion for g_6 is
calculated and resummed by means of the Pade-Borel-Leroy technique. Under the
optimal value of the shift parameter b providing the fastest convergence of the
iteration procedure the estimates g_6^* = 1.10, g_6^*/{g_4^*}^2 = 2.94 are
obtained which agree quite well with those deduced recently by S.-Y. Zinn,
S.-N. Lai, and M. E. Fisher (Phys. Rev. E 54 (1996) 1176) from the
high-temperature expansions.
