**Topics from today's class**:

- Representing knots as signed graphs

**Homework**:

- 2.27, 2.28, 2.29, 2.31 (Type III only)
- Pet knot: create a signed planar graph for your knot and put it on the wiki. In the justification box draw the signed graph on top of your knot projection. You do not have to shade the faces (although you can if you are able to figure it out). Note: there is no place for it on your pet knot page. Put it under the Conway notation.
- Don't turn in: 2.30

**Read for next class**:

- 3.2
