| | | | Introduction I see a lot of developers coming to Go from object oriented programing languages such as C# and Java. Because these developers have been trained to use type hierarchies, it makes sense for them to use this same pattern in Go. However, there are aspects of Go that don't allow type hierarchies to provide the same level of functionality they do in other object oriented programming languages. Specifically, the concepts of base types and subtyping don't exist in Go so type reuse requires a differ... | |

| | The First Isomorphism Theorem The meat of our last primer was a proof that quotient groups are well-defined. One important result that helps us compute groups is a very easy consequence of this well-definition. Recall that if $ G,H$ are groups and $ \varphi: G \to H$ is a group homomorphism, then the image of $ \varphi$ is a subgroup of $ H$. Also the kernel of $ \varphi$ is the normal subgroup of $ G$ consisting of the elements which are mapped to the identity under $ \varphi$. |
