This makes my head hurt. Surely Wittgenstein had permission to use Occam's razor? I mean, if it's possible that you actually meant quus_5 then it's equally possible that you meant quus_3 or quus_114, but since you didn't mention that, I will just assume you meant whichever requires the least amount of parameter-guessing from my side. After all, you have written it down for a human receiver, not for an alien from the Quus_8th dimension.
