Sep 4, 2013 at 7:40 comment added Moritz Firsching @Eric yes, that would be interesting indeed!
Sep 3, 2013 at 13:38 comment added Eric Wofsey Fascinating! From skimming the paper, it appears that their argument is entirely obstruction-theoretic and doesn't exhibit an explicit map when $n$ is not a prime power. I would love to see such an explicit construction.
