> The model village includes a scale model of the model village (which would be at 1:81 scale). This model, in turn, contains a scale model of the model of the model village; being at 1:729 scale this measures around 1 foot (30 cm) in width. This model also contains a scale model (in paint only) of the model of the model of the model village (which would be at 1:6561 scale).
Also, then noticed that the sqrt(10) is almost exactly 256/81, the 4th root of 10 almost 16/9, and the 8th root almost 4/3.
Too bad the Vegas sphere is 21:9.
But the URL seems to have been truncated to point to the whole article.
Apparently that was based on one at Wimborne - a copy of it, presumably.
