n+1 Group

An n+1 group is a mathematical concept used in algebra to describe a specific kind of group extension. It consists of a base group (n) and an additional element (the "+1") that extends or enlarges this base. Think of it like adding one more piece to a puzzle, creating a new, larger structure. In more formal terms, it’s a way to build a new group by combining an existing group with an extra element that interacts with the original in a defined way. This concept helps in classifying and understanding complex group structures in mathematics.
