COMC 2012 B Problem 3

Given the following 4 by 4 square grid of points, determine the number of ways we can label ten different points A, B, C, D, E, F, G, H, I, J such that the lengths of the nine segments

A B, B C, C D, D E, E F, F G, G H, H I, I J

are in strictly increasing order.

\begin{array}{cccc} \cdot & \cdot & \cdot & \cdot \\ \cdot & \cdot & \cdot & \cdot \\ \cdot & \cdot & \cdot & \cdot \\ \cdot & \cdot & \cdot & \cdot \end{array}
