Leinster's Category theory model answers

I belong to a group that is working through Leinster's book, and I have posted some solutions. I will be updating this from time to time.

Update: The group finished the book. A greatly expanded set of solutions is now available from my web page.

If anyone is interested, I also wrote down solutions to all exercises in the book (I was not aware of the other set of solutions above).

You can find them here: https://positron0802.wordpress.com/basic-category-theory-leinster/
