Gittin 80: So May Ways to Invalidate a Divorce

A long mishnah (or a series that are published together): If a get is written with a name of a place that is not legitimate... Or other goofs in location... If other details are wrong... When is the get not a get? Plus, how a get that is not a get can really mess up a second marriage, and children from the second marriage. Plus, co-wives are treated like the divorcing woman too. Also, a deeper dive into the country that is not legitimate, and other countries as named in divorce. Plus, Rabbi Meir's approach in creating mamzerim.
