If you divide the world into 3m x 3m squares (small enough for most practical purposes) then this gives you 57 trillion squares so…

– with 1 word you can uniquely name 40,000 3m x 3m squares, so that’s every 3m x 3m square in a small village. But the world is bigger than this so it would be a useless system.

– with a sequence of 2 words you can uniquely name 1,600,000,000 3m x 3m squares, so that’s every 3m x 3m square in an area the size of Hawaii. But the world is bigger than this so it would be a useless system.

– with a sequence of 3 words you can uniquely name 64,000,000,000,000 3m x 3m squares, so that’s every 3m x 3m square in the world (actually we have a few combinations spare).

– with a sequence of 4 words, we could uniquely identify every 3m x 3m square in an area 40,000 times the size of the world, but there would be no point.
