This ticket implements basic affine groups and Euclidean groups:
{{{
sage: G = AffineGroup(3, QQ)
sage: g = G.random_element(); g
[ 2 -1/2 0] [ 0]
x|-> [ 1 -1 -1] x + [-32]
[ 0 -2 -2] [1/3]
sage: g*g
[ 7/2 -1/2 1/2] [ 16]
x|-> [ 1 5/2 3] x + [ -1/3]
[ -2 6 6] [191/3]
sage: g*g.inverse()
[1 0 0] [0]
x|-> [0 1 0] x + [0]
[0 0 1] [0]
}}}
