Working on what VQC said he was going to explain to us seemed to be enough for him to taunt us with his presence yesterday, so I'll continue.
>Then we will look at the key that is made by column -f with the locations of c in (-f,1)
I'll start with the same two examples from my last posts, c=203 (729) and c=559 (1343). I'll just do the first in this post and probably do the other in the next post.
c=203, d=14, e=7, f=-22
Relevant n=1 records are (7,1) and (-22,1).
559 doesn't seem to come up as a, b or d in (-22,1), nor does it appear to come from some kind of equation between different variables. So I thought the only way I would see it explicitly come up was by extending the records until x=203 or t=203. x is always even for (-22, 1), so c only appears in relation to x as x+n or x-n (since n=1).
(-22, 1, 101) = {-22:1:20593:202:20391:20797} f=41163
(-22, 1, 102) = {-22:1:21001:204:20797:21207} f=41979
Blindly looking for c here, the difference between d values here is 408, which is (203+1)2, the difference between a values is 406, which is just 2032, and the difference in f values here is 816, which is (203+1)*4. So I guess you can technically find c here, when x is adjacent to c.
The only other way you can explicitly find c in (-f,1) is when t=c.
(-22, 1, 203) = {-22:1:82813:406:82407:83221} f=165603
Here also, we have 406 pop up again, which is 203*2.
So, yeah, c does kinda come up in (-f,1), as 2c when you make t=c. I'll have to see about the other one. I also don't see how this could be useful at all, but he mentioned it, so I guess I'll keep looking.
