Anons, just wanted to point out a few things with Qpost#1871.
Remember that awhile back, Q had asked us if we "counted the spaces". Little details like that matter, but it's hard to see them unless you look at the text in a monospaced font.
Pic related is the post, copied-and-pasted from the forums; I didn't bother counting the spaces here, but the periods in each group at the bottom of the diagram are different; there's 23 in the one to the bottom-left, and 25 in the one next to it.
Q mentioned 1:1:1:1; I'm taking that to mean a 1:1:1:1 correspondence. So we need to find four groups; however, we can't have a 1:1:1:1 correspondence if the two groups at the bottom have 23 and 25 members.
I don't know if it's just the autist in me, but looking at the post in monospace seems like it's off-kilter; it's as if there are entries missing. Is it possible that there's a missing group at the top, next to MOS? Maybe…C_A?
This is all just speculation, but it might help us to map out these connections.
