Detecting codimension one manifold factors with the piecewise disjoint arc-disk property and related properties

We show that all finite-dimensional resolvable generalized manifolds with the piecewise disjoint arc-disk property are codimension one manifold factors. We then show how the piecewise disjoint arc-disk property and other general position properties that detect codimension one manifold factors are related. We also note that in every example presently known to the authors of a codimension one manifold factor of dimension n a parts per thousand yen 4 determined by general position properties, the piecewise disjoint arc-disk property is satisfied.
