In this video, we introduce the notion of a group invariant, that is, a property that is preserved by an isomorphism. We demonstrate how to prove two groups are non-isomorphic by invariants. We also discuss some cases when a list of invariants determine the group. • This is lecture 26 (part 3/3) of the lecture series offered by Dr. Andrew Misseldine for the course Math 4220 - Abstract Algebra I at Southern Utah University. A transcript of this lecture can be found at Dr. Misseldine's website or through his Google Drive at: • https://drive.google.com/file/d/1g3CD... • This lecture is based upon Section 9.1 of Abstract Algebra: Theory and Applications (http://abstract.ups.edu/) by Tom Judson. Please post any questions you might have below in the comment field and Dr. Misseldine (or other commenters) can answer them for you. Please also subscribe for further updates.
