Distinction between greatest element, maximal element and maximum[edit]
maximal element is not subclass of (P279) of supremum (Q215071). e.g. {0} and {1} are maximal elements of ({φ, {0}, {1}}, ⊂), but they are not supremum (Q215071). supremum (Q215071) is {0, 1}. Seeing the English label description "maximal element" and corresponding properties, it is apparently appropriate to remove the subclass of (P279) statement (And I did so). However, maxima and minima (Q845060), whose English description is "largest and smallest value taken by a function in a given range", says that is disjoint union of (P2738) maximum (Q10578722) and minimum (Q10585806). There are lot of statements each of which uses this entity as a qualifier in the context of greatest element or functional maximum. Therefore, this entity should be understood as the union concept of greatest element, maximal element, and maximum, that is, greatest element (Q79674627), maximal element (Q111315902), and maximum (Q111305333) --KAMEDA, Akihiro (talk) 09:55, 20 March 2022 (UTC)
