# laurent_C4_w7-12.txt -- Laurent polynomials at the cusp of the 49 two-vertex four-edge modular graph functions # C_{a,b,c,d}(tau) of weights w = a+b+c+d = 7..12: C = sum_k c_k y^k + O(e^{-2y}), y = pi Im(tau), 1-w <= k <= w. # One line per NONZERO coefficient: a b c d k c_k (coefficients absent for a listed function vanish exactly). # c_k is an exact rational combination of: zeta(n) = Riemann zeta value; zeta(2)^j; zeta(n1,n2) and zeta(n1,n2,n3) = # multiple zeta values in the ASCENDING convention zeta(n_1,..,n_r) = sum_{0
