The very fact that you don't know should tell you that it is interesting, as figuring out yourself which case applies is already a challenge.

There is also an hint. Werner went throughthe numbers up to magnitude 10^34 in likely some hours or days , do you estimate it can be brute force?


Also little note, if it is not interesting, ignore it. There are billions of uninteresting discussions online, we don't go writing around that we are not interested. Writing that we are not interested is first and foremost uninteresting (nobody asked us) and secondly it sounds a tad confrontational.
