There is a relation between rectilinear-adjacent squares such that there is a unique rectilinear path from the top-left corner of the grid down to the bottom-right corner of the grid. Each square can participate in the path no more than once. What is the relation and the path it induces?

- Follow the path of relation through the grid #1
- Follow the path of relation through the grid #2
- Follow the path of relation through the grid #3
- Follow the path of relation through the grid #4
Hint 1
The relation is inspired by a Project Euler puzzle.
Hint 2
The relation pertains to whether adjacent numbers are part of the same triplet.
