Resources for Sage & Cocalc:

• Sage Quick Reference,
• Graph Theory Quick Reference,
• Linear Algebra Quick Reference,
• Abstract Algebra Quick Reference,
• Calculus Quick Reference,
• Dynamics Quick Reference,
• Differential Equations Quick Start,
• Programming in Python,
• Computational Mathematics with SageMath book.
• Here is a blank hex paper, useful for drawing benzenoid graphs.
• The Cocalc (Sage Math Cloud) server, the program I use for Mathematical Computing (MATH 255).
• A Sage for Undergraduates Book by Gregory Bard (Here is an uncompressed pdf of the book).
• The Sage project website, with FAQs, downloads, and lots of information.
• Sage help videos by William Stein.
• Sage Quick Reference Cards.
• Rob Beezer's Linear Algebra in Sage
• William Stein's Sage for Power Users (pdf).
• SDSU Programming in Sage tutorial
• Code Academy Python tutorial. Codeacademy.com is a great place to dive in to learning programming languages. Sage is written in Python. So its a great idea to work through the Python tutorial.
• A good Khan Academy video Python tutorial.

Resources for Graph Theory

• House of Graphs, is a place to go to find information about a specific graph or class of graphs, and to add graphs that might be of interest to others.
• Grinvin is a free computer program that can be used to calculate invariants, generate graphs, and otherwise explore.
• Here's the House of Graphs app for putting in a graph and generating its graph6_string.
• An amazing resource for Graph Classes.

Good free Graph Theory books online:

• Diestel's Graph Theory (modern).
• Bondy and Murty's Graph Theory with Applications (classic).
• Wilf's Algorithms and Complexity (undergrad).

Graph Theory & Combinatorics in Sage/Cocalc:

• Nathan Cohens' Graph Theory in Sage
• Sage Combinatorics Tutorial
• William Stein Graph Theory in Sage video (Dr Stein is using the Sage notebook and not Sage Cloud - but most things are the same)

Other Stuff for Current Students:
