| Aug 5, 2011 at 22:31 | comment | added | JSE | Oh, and in this respect (my forgetting to think about the decomposable locus) Dan's point is also germane. The question of whether universal genus-2 curves over Shimura curves are 4-branched covers remains active, though! | |
| Aug 5, 2011 at 22:29 | comment | added | JSE | My comment is that I forgot to think about the decomposable locus, so thanks for working this out! Re the qualms with Ben's argument, surely it can't be fully right because both Ben and Jason gave examples of compact families of 4-branched covers. | |

The genus of $X^{218}$ is 10 while the genus of $X^{842}$ is 36.
