Théories spectrales, chapter I, § 6. Algèbres stellaires

In general, the Banach involutive algebra M1(G)\mathscr{M}^1(G) (example 4 of I, p. 100) is not a stellar algebra (I, p. 181, exerc. 8).

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
