External Direct Product Examples: ℤ2 ⊕ ℤ3, ℤ2 ⊕ ℤ3 ⊕ ℤ5, and ℤ2 ⊕ ℤ3 ⊕ ℤ6

What are the elements of ℤ2 ⊕ ℤ3 and what are their orders? Is ℤ2 ⊕ ℤ3 a cyclic group? How about ℤ2 ⊕ ℤ3 ⊕ ℤ5? How about ℤ2 ⊕ ℤ3 ⊕ ℤ6? Use the fact that the order of an ordered pair (a,b) is the LCM of the orders of the components a and b, and the order of an ordered triple (a,b,c) is the LCM of the orders of the components a, b, and c. 🔴 "Contemporary Abstract Algebra", by Joe Gallian: https://amzn.to/2ZqLc1J 🔴 Abstract Algebra Exam 1 Review Problems and Solutions:    • Abstract Algebra Exam 1 Review Problems an...   🔴 Abstract Algebra Exam 2 Review Problems and Solutions:    • Abstract Algebra Exam 2 Review Problems an...   🔴 Abstract Algebra Exam 3 Review Problems and Solutions:    • Abstract Algebra Exam 3 Review Problems an...   🔴 Abstract Algebra Final Exam Review Problems and Solutions:    • Abstract Algebra Final Exam Review Problem...   🔴 Abstract Algebra Problems with Solutions (including Proofs):    • Abstract Algebra Problems with Solutions (...   🔴 Abstract Algebra Lectures Playlist:    • Abstract Algebra Course, Lecture 1: Introd...   🔴 Check out my blog at: https://infinityisreallybig.com/ #AbstractAlgebra #DirectProduct #GroupTheory Links and resources =============================== 🔴 Subscribe to Bill Kinney Math: https://www.youtube.com/user/billkinn... 🔴 Subscribe to my Math Blog, Infinity is Really Big: https://infinityisreallybig.com/ 🔴 Follow me on Twitter:   / billkinneymath   🔴 Follow me on Instagram:   / billkinneymath   🔴 You can support me by buying "Infinite Powers, How Calculus Reveals the Secrets of the Universe", by Steven Strogatz, or anything else you want to buy, starting from this link: https://amzn.to/3eXEmuA. 🔴 Check out my artist son Tyler Kinney's website: https://www.tylertkinney.co/ 🔴 Desiring God website: https://www.desiringgod.org/ (0:00) ℤ2 ⊕ ℤ3: Elements and their orders (8:27) |(a,b)|=lcm(|a|,|b|) (13:28) ℤ2 ⊕ ℤ3 ⊕ ℤ5: Number of elements of various orders (21:34) ℤ2 ⊕ ℤ3 ⊕ ℤ6: Number of elements of various orders (28:48) Number of cyclic subgroups of order 6 in ℤ2 ⊕ ℤ3 ⊕ ℤ6 AMAZON ASSOCIATE As an Amazon Associate I earn from qualifying purchases.
