I'll start with GFN7 and 11 for n>=201 up to limit of mmff-gfn v.0.28 (252 bits).

You will find two new tables above (GFN7 between GFN6 and GFN10, and GFN11).

I will update current known limits for n<=200 for these ranges when I will find them exactly; for now, it is known from Keller's table thus:

Code:

n Limit for k
26-50 2*10^12
51-100 1*10^12
101-200 100*10^9
201-300 15*10^9
