This is the collection of all five-sided polygons. Pentagon A predicate that is used to make exceptions to constraints normally imposed by some instance of <a href="http://sw.opencyc.org/concept/Mx4rvViA4pwpEbGdrcN5Y29ycA" class="cyc_term">SiblingDisjointCollectionType</a> or <a href="http://sw.opencyc.org/concept/Mx4rk8dxOFcGEdaLwgACs0uFOQ" class="cyc_term">SiblingDisjointSetOrCollectionType</a> (qq.v.). <code>(<a href="http://sw.opencyc.org/concept/Mx4rwQtVmpwpEbGdrcN5Y29ycA" class="cyc_term">siblingDisjointExceptions</a> SETORCOL1 SETORCOL2)</code> means that the pair consisting of <code>SETORCOL1</code> and <code>SETORCOL2</code> is exempt from the disjointness constraint that would otherwise be imposed because those set-or-collections are both elements of some instance of <a href="http://sw.opencyc.org/concept/Mx4rvViA4pwpEbGdrcN5Y29ycA" class="cyc_term">SiblingDisjointCollectionType</a> or <a href="http://sw.opencyc.org/concept/Mx4rk8dxOFcGEdaLwgACs0uFOQ" class="cyc_term">SiblingDisjointSetOrCollectionType</a>. (See these collections' comments for a full explanation of the constraints.) For example, <a href="http://sw.opencyc.org/concept/Mx4rv0GdXpwpEbGdrcN5Y29ycA" class="cyc_term">SensoryNerve</a> and <a href="http://sw.opencyc.org/concept/Mx4rvWvJVpwpEbGdrcN5Y29ycA" class="cyc_term">CranialNerve</a> are both instances of <a href="http://sw.opencyc.org/concept/Mx4rwKTnSJwpEbGdrcN5Y29ycA" class="cyc_term">OrganismPartType</a>, which in turn is an instance of <a href="http://sw.opencyc.org/concept/Mx4rvViA4pwpEbGdrcN5Y29ycA" class="cyc_term">SiblingDisjointCollectionType</a>. Consequently, since <a href="http://sw.opencyc.org/concept/Mx4rv0GdXpwpEbGdrcN5Y29ycA" class="cyc_term">SensoryNerve</a> is not a specialization of <a href="http://sw.opencyc.org/concept/Mx4rvWvJVpwpEbGdrcN5Y29ycA" class="cyc_term">CranialNerve</a> (or vice versa), the two collections have a default disjointness constraint placed between them. However, such a disjointness constraint should be blocked, since any instance of <a href="http://sw.opencyc.org/concept/Mx4rvVjLm5wpEbGdrcN5Y29ycA" class="cyc_term">OpticNerve</a> is an instance of both <a href="http://sw.opencyc.org/concept/Mx4rv0GdXpwpEbGdrcN5Y29ycA" class="cyc_term">SensoryNerve</a> and <a href="http://sw.opencyc.org/concept/Mx4rvWvJVpwpEbGdrcN5Y29ycA" class="cyc_term">CranialNerve</a>. By asserting <code>(<a href="http://sw.opencyc.org/concept/Mx4rwQtVmpwpEbGdrcN5Y29ycA" class="cyc_term">siblingDisjointExceptions</a> <a href="http://sw.opencyc.org/concept/Mx4rv0GdXpwpEbGdrcN5Y29ycA" class="cyc_term">SensoryNerve</a> <a href="http://sw.opencyc.org/concept/Mx4rvWvJVpwpEbGdrcN5Y29ycA" class="cyc_term">CranialNerve</a>)</code>, we block the disjointness constraint between those two collections, without disturbing the constraints between each of those collections and all their other (sibling) instances of the parent collection <a href="http://sw.opencyc.org/concept/Mx4rwKTnSJwpEbGdrcN5Y29ycA" class="cyc_term">OrganismPartType</a>.
