  consider two sets: set a and set b. both set a and b contain all horses, ane nothing else. they are always equivalent.

    Sure, but does the set of all sets that don’t include themselves include itself?

      Easy. If and only if the integer sequence A053169 contains itself.

    But how can set b contain all of the horses if they’re already in set a???

      Obviously there’s the overall juxtaposition, but I really like the proportional dampness.
