This would seem to be a trivial question, but with the current structure of puzzling.SE I'm legitimately not sure: I have a question that's a variant on another puzzle previously asked on the site; the difference is that I don't know the answer to my variant. The question would be reasonably appropriate either here or on the mathematics SE site, but given that the original problem was here, puzzling.SE seems an appropriate site for a followup. Still, the fact that I don't know the answer does seem to complicate matters, and I want to be certain that it's an appropriate question to be asking 'can you figure out the answer?' of here even if I don't know the correct answer (yet) myself.
An update, for the curious: I decided once the question was written up that it was more mathematical in nature and that I was primarily interested in the mathematical content rather than the puzzle content, so I've gone ahead and posted it over on mathematics.SE.
