That's my point about noticing there's only a single square from which you can reach more than two others. It follows that there's only one square where you have more than one choice other than...

Here's the program I used and some notes: Sizes 2 or 3 mod 4 like 22/23 are actually easier to calculate: for such sizes, the result is just half the total polyomino count (which you can look up...

There are some things I'd say about the calculation, but they'd be kind of spoilery, so perhaps better left for private messages or after the month is over.

I've computed up to 23 (with a fast enough program that calculating the next few values would be realistic if I left it running for a while).

If you don't go through all the numbers to check whether it is of the given form, but instead just flip each odd square times a power of two (go flip 1, 1*2, 1*4, ... until you go over the total...

That seems unnecessarily clumsy. If you want to divide it like this, 4 categories is enough (for each combination of the two criteria I gave). Some of...

Note that you can permute the order of x_i arbitrarily if you also permute y_i the same way. Take the example solution given in the problem statement and order the x_i in ascending order: x =...

This is a rather vague description, but I assume you mean changing the lockers divisible by 3 (and not changing starting from locker 1, and then every third from it). If you always start from the...

Even that is slower than necessary - there's a straightforward O(n2) algorithm. By the way, the way to present the problem feels slightly weird to me - the introduction about how every size 2n set...
