Elimination 44 Elimination 44 to is another example of a single rank 0 linkset in a big structure. The overall structure is rank 0 but cannot eliminate candidates because the set triplets at 2r1c2, 2r1c3, and 6r6c5 can all potentially raise the rank. However, the box linkset 5b6 sits on the linkset (minor) side of all set triplets and its rank cannot be lowered by the set triplets resulting in the elimination.
