If M is any irreducible stationary Markov chain on the set of computable permutations of the natural numbers, then M is transient.

• KnaveOfAllTrades estimated 80% on 2015-05-31
• orthonormal said “I, um, forgot to say that M had to have stationary transition probabilities. That kind of makes the difference between true and false. What should I do with this prediction?” on 2015-05-31
• KnaveOfAllTrades said “It sounds like in the spirit of the prediction you meant to make, you were correct. But in the spirit of the prediction I made (IIRC I decided in advance I’d be wrong even if you omitted or misstated the hypotheses), I was incorrect.” on 2015-05-31
• KnaveOfAllTrades said “So maybe leave this unmarked and we each make a new prediction? I’ll leave it up to you ultimately.” on 2015-05-31
