Interesting how Frits Göbel found so many in 1979, including some larger n, but some smaller n eluded him, found by others decades later.

Not clear from this page whether he found results for smaller n that better solutions were found for later, or not at all. Presumably one would have to read his paper to see, but I can't find it.
