Now that the "Numberphile" YT channel has revealed the answer to the life, the universe and everything:

I had to check it with my DM42. Well, it cannot calculate it's own self ;) :D

Yes WP43S can! :P

But DM42 can calculate 43 :D 12^3 + 8^3 + (-13)^3

You can simplify the example for the testSuite for 43 (2^3 + 2^3 + 3^3), but I think for 41 there is no solution.

It seems proven that there is no solution for 41
