The 2x2 case is impossible, I suspect it is related in some way.

Seems this is related to Hamiltonian path problems. The issue is there is always one square that can’t be picked up. Why could this be?
I am afraid that I didn’t apply any rigor here and thought I solved it. Been playing with it for a bit and see there is likely not a solution. Good fun for me.
Rooks don’t move diagonal. I was able to do this exercise in my head on about the third try however. Start with big laps round the outside x2, then column by column to finish
Both of the proposed have ingredients that cook and char to solids if you cook them at temperatures you want to fry at. You need something that can take the heat and transfer it. You need a fat or an oil. Maybe a heavy sugary water like applesauce could be used but it’s not boiling than frying.
Crime motive is subjective, judges are subjective, justice is an ideal that is served by mins and maxes. I can’t fall on either side of the question totally but I do think objective punishments for objectively proven crimes seems more just.
This is everything
I laughed but now I’m sad
Robert miles -children love it, the whole album. sound dated now but the return to that time is real when I hear it.
If you take the rooks movement, and reduce each longer move to a series of single steps a1a2a3a4 for example, this becomes a Hamiltonian problem. The corners have 2 nodes, the edges three, and the core has four. Black and white indicates even or uneven distance in nodes.
