It is shown that the h ‐vectors of Stanley–Reisner rings of three classes of matroids are pure O‐sequences. The classes are (a) matroids that are truncations of matroids, or more generally of Cohen–Macaulay complexes, (b) matroids whose dual is (rank+2) ‐partite, and (c) matroids of Cohen–Macaulay type at most 5. Consequences for the computational search for a counterexample to a conjecture of Stanley are discussed.
