Can you please clarify what you mean?

The story about Bill Tutte has nothing to do with Enigma. Yes, Bill Tutte worked at Bletchley, and so did the code breakers who worked on Enigma.

But Tutte worked on Lorenz, and this story is about Tutte and his work, and hence this story is not about Enigma.
