Summary
| Description |
English: Illustration of the extension of Q by N, resulting in the group G. They form a short exact sequence 1 -> N -> G -> Q -> 1. The injective map ι (iota) maps N to a normal subgroup of G. In turn, the map π maps G onto Q, sending each coset of ι(N) to a different element of Q. |
