Abstract
We refer to the discussion on different characterizations of the class of weights, initiated by Duoandikoetxea, Mart\'in-Reyes, and Ombrosi. Twelve definitions of the condition are considered. For cubes in every two conditions are known to be equivalent, while for general bases we have a trichotomy: equivalence, one-way implication, or no dependency may occur. In most cases the relations between different conditions have already been established. Here all the unsolved cases are treated and, as a result, a full diagram of the said relations is presented.
