Definition

Symbol-free definition

An algebra loop is said to be simple if it has no proper nontrivial normal subloop. In other words, the only normal subloops are the whole loop and the trivial element.

Analogy

The definition of simple loop generalizes, to algebra loops, the definition of simple group for groups.

Recall that a group is said to be simple if it has no proper nontrivial normal subgroup. The analogue of normal subgroup in algebra loops is normal subloop, and this explains the definition of simple loop.
