We've kind of gotten out of sequence here!
This week, the main thing is to figure out what most of the names of the orbifolds mean and what most of the orbifolds are. Next week we'll find out why these are the only orbifolds possible.
The subsymmetry part is very interesting, but time is running out. Give this less attention.
