Yes, it does not work on all numbers but on most of them. Your results look similar to mine. I estimated the "benalty" for kN == 1 (mod 8) from a scatter plot of f(k1)-f(k*) vs....

that's a good new option for me. If the number of cycles reported by our counting algorithm is an upper bound of the true cycle count, then we only need to run the matrix solver when the...

Does that mean that higher-dimension approaches that do not *somehow* project to this solution in 2 dimensions could be ruled out? That could save a lot of money in string theory...

So far I haven't been collecting exactly the same data, but lets see.
