Issue:: There's subtle question here: what defines the membership of the elements subposet? For instance, is it all the triangle shaped cells, or just the finest ones that are also jims? We're following the latter definition. The elements subposet is frequently used as an evaluation subposet and we don't want non-jims showing up as evaluators.
