Abstract

We evaluate multiple polylogarithm values at sixth roots of unity up to weight six, i.e. of the form G(a1,,aw;1)G(a_1,\ldots,a_w;1) where the indices aia_i are equal to zero or a sixth root of unity, with a11a_1\neq 1. For w6w\leq 6, we present bases of the linear spaces generated by the real and imaginary parts of G(a1,,aw;1)G(a_1,\ldots,a_w;1) and present a table for expressing them as linear combinations of the elements of the bases.
