Tag 0AR2, permanent. Cite it as [Bourbaki, Tag 0AR2].

Lie Groups and Lie Algebras, chapter V, § 3. Groups of displacements generated by reflections

The set L(a)L(a) is contained in the set of special points, but in general is distinct from it (cf. Chap. VI, § 2, no. 2 and Plates I to VI).

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
