We revisit a critical point in the solve of this monstrous puzzle, where a number of eagle-eyed viewers noticed that a uniqueness situation might arise. We take a look at this again to see whether this would have been a short cut to the solution.

If any of our viewers would consider sponsoring us on Patreon we would be extremely grateful. A Patreon button should pop-up at the end of the video; or, alternatively, our Patreon Page can be found here:
