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

$X_{1}^{c}  \cup X_{2}^{c}$

X₁^c∪X₂^c, where for any MATH

$A \subseteq O, A^{c} = O \setminus A$

A⊆O, A^c = 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.

gloss words

• set union hash operator
