### Network Description for Moving Down

In the Moving Down puzzle, the major object of interest is a diagram of points and lines. This page describes this diagram textually.

There are sixteen points, arranged into a four by four lattice with equal distances between the rows and the columns. Each point is connected by lines to the points immediately to its right and its left, and immediately above it and immediately below it. The entire lattice is then rotated 45 degrees to form a diamond pattern.

The top point (the starting point of paths through the lattice) is labelled 1. Point 1 connects to point 2 by going down and left, and point 3 by going down and right. Point 2 connects to point 4 by going down and left, and point 5 by going down and right. Point 3 connects to points 5 (left) and 6 (right). Point 4 connects to points 7 (left) and 8 (right). Point 5 connects to points 8 (left) and 9 (right). Point 6 connects to points 9 (left) and 10 (right). Point 7 connects to point 11 only, by going down and right. Point 8 connects to points 11 (left) and 12 (right). Point 9 connects to points 12 (left) and 13 (right). Point 10 connects to point 13 only, by going down and left. Point 11 connects to point 14 only, by going down and right. Point 12 connects to point 14 (left) and 15 (right). Point 13 connects to point 15 only, by going down and left. Point 14 connects to point 16 only, by going down and right. Point 15 connects to point 16 only, by going down and left. Point 16 connects to no other points.
