## Errata.

Please see this list for the errata reported before June 2010. Here are the errata that have been reported since November 2011. For brevity, we have suppressed the spelling and grammatical errors. This list is for errors in the text. Errors in web content are just fixed when reported; errata in lectures are listed here.

**9.**Coefficient in third term on line 5 should be 1/12 (Steve Kroon 10/4/13)**32.**Last two elements in $G^[3]$ are incorrect (missing root nodes in inner sequences).

See description of similar error for unlabelled objects on page 87.
