For PMA's diagram, the math is as follows:
1+ (f-1) + (n-1) = 169
1+ 133 + 35 = 169
The earlier n0 value would have been n0 = 10
1 + 133+ 10 = 144 = SQRT(144) = 12
The next value would be n0 = 62
1 + 133 + 64 = 196 = SQRT(196) = 14
Not sure if this works. Just brainstorming over here and keeping my mind locked on the happiness of finding the correct path! All comments and corrections appreciated.
