    "abstract": "The consistent histories formalism is discussed using path-projected states.\nThese are used to analyse various criteria for approximate consistency. The\nconnection between the Dowker-Halliwell criterion and sphere packing problems\nis shown and used to prove several new bounds on the violation of probability\nsum rules. The quantum Zeno effect is also analysed within the consistent\nhistories formalism and used to demonstrate some of the difficulties involved\nin discussing approximate consistency. The complications associated with null\nhistories and infinite sets are briefly discussed.",
