We quantify certain features of algebraic triangulated categories using the ‘ n ‐order’, an invariant that measures how strongly n annihilates objects of the form Y / n . We show that the n ‐order of an algebraic triangulated category is infinite, and that the p ‐order of the p ‐local stable homotopy category is exactly p −1 for any prime p . In particular, the p ‐local stable homotopy category is not algebraic.
