It'd be interesting to see how the various functions perform with
respect to that polynomial for large n. They may well implement it.

Unless I've made a mistake, the polynomial indicates the sum of all the
entries in a 46341 by 46341 multiplication table is 1152866771266955745. 
This is the largest solution that fits in a long variable. The answer is
reported in less than 1 ms.
