This entry has passed review, but has not reached its final version, amendments will be made as require by ancillary entires.

Entry Level 3 (final) -- To be appended.

Entry Level 2 (semi-final) -- I've had to revise the design once again. Note to self: In the future, do research before drafting! It will save a lot of time LOL. The new specification for the geosphere involves equilateral triangles; see unit for a more detailed dimensionality. Mettos are now triangular in shape. One of the nice side-effects of this change is that it means an increase in the proportion of walk and overall circulatory system (transportation network) density. There are several advantages to this new arrangement, including that it makes the internal area of the metto a lot more accessible from the outside, and even cross-metto navigation is improved. The effect is really quite dramatic in comparison to the previous geometry, which ended up creating huge areas within each metto that were essentially isolated and remote.

Entry Level 1 (intermediate) -- Due to my limited understanding of geometry the geosphere design has been amended. The new configuration is similar to that of a soccer ball. Mettos are hexagonal in shape rather than square, like a honeycomb rather than a grid. There are still however one billion mettos total. Obviously the surface area of each metto will have to be adjusted in order to compensate for the proportional increase in area that comes with adopting a hexagonal rather than square polygon.

Entry Level 0 (beta) -- The city planet is defined by an artificially created 'world' or 'earth' made entirely out of polytoy. While in reality the planet as a whole is made up of many layers and components that are all bonded at the molecular level, at various strategic junctions (for structural integrity purposes); the primary foundation is a single spherical construct commonly referred to as the geosphere or less commonly the "neosphere".

The geosphere is a spherical, isometric matrix comprised of square sections, like tiles or plates. Each plate constitutes a metto, and has a unique name. Theoretically there are one billion mettos total that make up the entire geosphere. These plates are both divided and joined by narrow interconnected channels that are called the walk.
