Munroe numbers

This page shows some statistics on the meetup graph including all finite Munroe numbers and all finite Thomcat numbers. The heavy lifting is being done by Hijackal, who provides a machine-readable version of the meetup graph, and by Graphviz's dijkstra tool.

Maximum distance

This table shows the maximum distance from any geohasher to any other geohasher on the interconnected part of the meetup graph. It is a measure of how central a geohasher is on that graph. Randall Munroe is not the best center, the maximum Munroe number is 10. A better center is Thomcat, with the maximum Thomcat number being 6.
