definition
binary mekso operator: Let the inputs X1 and X2 be sets in the same universal set O; then the result of this operator applied to them is MATH
$X_{1}^{c} \cup X_{2}^{c}$
X1c∪X2c, where for any MATH
$A \subseteq O, A^{c} = O \setminus A$
A⊆O, Ac = O <img alt="$\setminus$" src="/jbovlaste_export/9PjmACiaYt/img1.png" style="height: 2.38ex; vertical-align: -0.70ex; "/> A.
notes
Generalizes to n-ary, for any integer n>1 or n being an infinity. This operator generates all three of the basic set operators: union (jo'e), intersection (ku'a), and relative complement (kei'i). See also: xa'ei'u. .krtis. calls it the "union(-type) hash operator", but has never seen a generally used name for it.
