For #7, the 'glide reflection is half the length of translation' problem, I've tried another way to make it less confusing. Steve had a parenthetical remark there which was kind of ungainly, and also partially incorrect. It's important that the students understand that a glide reflection can only occur when there is no reflection with the same axis - otherwise, you've got a translation and a reflection, separately.
