Скачать или смотреть Total number of subgroups of A4|Permutation group|Part 19|Lecture 79|Group Theory|Theta Classes

In this lecture we are going to find total number of subgroups of A4. First we recall the structure of A4 and then with the help of Lagrange's theorem find the possible order of subgroups of A4 and then we will see the number of subgroups of particular order in A4.
