WebJan 10, 2024 · 1 In case you have not seen Lagrange's theorem yet: as Chickenmancer says, a left coset of H in G is just the set consisting of all the elements of G of the form g ~ h for some fixed g ~ ∈ G and for every h ∈ H (this, for instance, would just be the left coset denoted g ~ H ). WebIn Exercises 3 and 4, let G be the octic group D4=e,,2,3,,,, in Example 12 of section 4.1, with its multiplication table requested in Exercise 20 of the same section. Let H be the subgroup e, of the octic group D4. Find the distinct left cosets of H in D4, write out their elements, partition D4 into left cosets of H, and give [D4:H].
