Found something cool!
c145 in (e,n) and (-f,n):
13^2 =169, and e = -24 brings that back to c145
12^2 + e of 1 = 145
e,n f=24
Then it switches in negative e
e=-24
And then f changes to 51 for -f record
The key value is 25
“Difference in remainders”
Difference between -24 and 1 is 25.
The difference is 25, and the sqrt is a
(At least for this example)
5,29
5 * 29 = 145
