@ereliuer_eteer Unless this is Axiom of Choice weirdness, there has to be at least two such digits, or you would run out of digits to use in the infinite decimal expansion.
@terrajobst@ereliuer_eteer If there was a digit that didn't appear an infinite number of times, that would mean that if you look at the infinite decimal expansion after its last appearance, that number never appears again in the infinite remainder of the decimal.
@terrajobst@ereliuer_eteer A digit appearing an infinite number of times doesn't mean it's an infinite repetition; it just means that the non-terminating decimal never runs out of any digit.
