An Illustrated Introduction to

Topology and Homotopy

Illustrations and Tidbits

1. Work in progress. Incomplete plus this clearly needs cleaning...

2. I will use this page for noting 'typos' and typos in the book. These can be found in the pdf behind thefollowing link: ERRATA! So far we have found 27 typos and 'typos'.

(There is a solution manual associated with this book, part 1 (published by CRC, 2017). Here is the Errata-Solution-Manual file!)
