>Well the triple U (not sure why they use that) The machine works a bit weirdly, in that as you find some correct settings, your results converge towards the legible result. You can get 95% of the settings correct, and produce quite legible results, at which point you stop solving. So the correct result there might actually be any other three char combo like "ABC" or "UAK", but the analyst stopped investigating, because the rest of the message was reasonably legible.
