Spacing

Spacing

In New groups from old, the spacing of the text in the section Graphs of groups seems oddly squashed, compared to other sections. I don't think I'm imagining it (though it's certainly possible)! Any thoughts?

You're quite right. The cause is the double dashes in the text $G''$ in the preceding the section; I have changed it to $G' '$ as a temporary fix. Unfortunately, the permanent solution will take a while to arrive!
