Unlike other people, I don't have a ready set of graph algorithms ready, so I tried a bit to implement Karger, before I went back and simply added -Kneato to my dot graph output and then the edges to cut became very clearly visible. I could have saved a couple of hours.

Day 24. This was a mad thing. I hate you all for using term solving tools under python. Thanks to the other kotlin guy who went the chinese remainder path and give a good amount of inspiration (strangely, the test input fails). I was thinking that some sort of modulo arithmetic could solve it, but it was too hard to figure out. What a waste of an otherwise nice xmas day.
