@ProducerofBS I didn't vote to delete earlier, but now I have, because it's still wrong; before you use the term "first X" you have to prove that "at least one X exists". Neither id you prove it nor can it be proven, because 0.3030303... (base 4) has no digit 1 or digit 2.
Ugh... this guy is really trying to write a good question, but s/he is getting contradictory advice from several different people (including someone who cynically suggested "Hey, pretend that you are looking for proof verification!").
I would have voted to reopen the previous iteration, but the current version of the question (in my opinion) contains too much fluff. @AloizioMacedo and I have weighed in on the comments; does anyone else feel like contributing?
How many delete votes would be needed to delete this question (with 322 upvotes)?
@XanderHenderson Something like 10? In any case, Based on my personal criteria it's an acceptable question, but I can see why it is off-topic to some other people.
