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^n-1 and (k^2*4^n+k*2^n+1)/7

or

(k*2^n-1)/7 and k^2*4^n+k*2^n+1

For R9, these formulas are either

(k*3^n-1)/2 and (k*3^n+1)/4

or

(k*3^n-1)/4 and (k*3^n+1)/2

For R12, these formulas are k*12^n-1 and k*12^n+1 (since for all these addition k (25, 27, 64, 300, 324), gcd(k-1,12-1) = 1)
