I agree, Anon! This is a feature of the catalog of values for var a VQC has mentioned. My focus is solving the generation of a values in row 1. Key issue is, starting from only c, how do we derive a? In row 1 (0,0) a = 2. For odd e, at t=1 a=(e+1)/2. For even e, at t=1 a=e/2. This gives us the starting seeds for all of row one and also allows us to derive x, t, b, and hopefully n as well.
Another issue we're dealing with is column 0 and how to use the grid to find products of c and c^2. Finding these patterns in conjunction with knowing how to generate the seeds of var a will be a big step forward! Seems like PMA, Teach, other anons, and yourself are working on this and making progress. I also think your idea about new factors only appearing from that point forward in the chain of a values is cool. I'll check it out, and thanks for your work!
