Update files for R8, R9 and R12, if you need them.
Only R12 k=300 remain.
Note:
For R8, these formulas are either
k*2^n1 and (k^2*4^n+k*2^n+1)/7
or
(k*2^n1)/7 and k^2*4^n+k*2^n+1
For R9, these formulas are either
(k*3^n1)/2 and (k*3^n+1)/4
or
(k*3^n1)/4 and (k*3^n+1)/2
For R12, these formulas are k*12^n1 and k*12^n+1 (since for all these addition k (25, 27, 64, 300, 324), gcd(k1,121) = 1)
