By the end of a two-month computation you get a result similar to equation 4.5 in this paper: https://arxiv.org/pdf/1707.01044 An exact answer is desired since the final result reveals some structure that can be studied, and because it is very hard to get a numerical result due to the occurrence of spurious poles. For example, evaluating (1-x)/x - 1/x numerically is challenging around x=0 even though symbolically it can be…</p><p><a href="https://hackerpaper.kaipfister.de/p/1707.01044/">Paper and discussion history</a>.
