Things have been a little quiet lately on this blog; I was away for a bit on vacation, and I’m still catching up on some things, and I know Vishal has been busy. Hopefully we’ll have more posts soon.

In any case, it’s high time for another Problem of the Week! This one is undoubtedly classical in nature, but may require a famously nontrivial result to solve quickly by hand:

Find the length of the period of the repeating decimal representation of \displaystyle \frac1{65537}.
