The PDF is accompanied by this video. It follows Abstract Algebra by Dummit & Foote.

We’d like to keep our videos free of interruptions and sponsors, so that the sole focus is the subject at hand. But in order to do that we need your help.

If you find value in our videos and would like to support our work further, and get very useful info that is unavailable anywhere else, consider purchasing this Full PDF on Group Theory

This Full PDF will explain why all cyclic groups of the same order are structurally the same (isomorphic), using concrete real-world analogies. We will later transition into formal definitions and extensive rigorous proofs, and will walk you through finite and infinite cyclic groups, homomorphisms, bijections, and proofs of isomorphism, and then reinforce your understanding with worked examples and exercises. We will also look at the broader landscape of group theory by briefly introducing symmetric, dihedral, general linear, and abelian groups. Thank you for supporting our work!

Thank you for supporting our work, it means a lot to us!

In any case, if you don’t have the means, we always have our free videos. Thanks again!
