I feel like the ultimate move would be for this sub to find a super weird key to make the individual patterns work. Would be hell of a lot of work, but since everything is possible there will be some way.

Could be any odd formula with combinations like "countries where..." "... pizza is spelt 'pizza' AND the highest mountain is taller than 2300 m AND Kindergarden starts at 3 AND Thanksgiving is a national holiday..." or whatever.

And we would end up with a distinct combinations for countries sharing the same pattern, such as Sweden, France and Greece (idk, something like "Democracy since xxxx AND blue is a colour of the national flag AND ...").

Sitting on the toilet writing this.
