62.
First, you need to find the "star" point which is located about 3.6 units from the edge.
If you want to count it from the first grid near the edge, then it will be exactly 3 units.
If we consider this star point as a coordinate origin (0, 0) of xy-system, then the "diamond" point will be at (1, -2).
Prepare for a mountain-fold along the blue line starting from the star and ending at the diamond.
