  A quandle is an algebra whose axioms are motivated from knot theory. A linear
extension of a quandle can be described by using a pair of maps called an
Alexander pair. In this paper, we show that a linear extension of a multiple
conjugation quandle can be described by using a pair of maps called an MCQ
Alexander pair, where a multiple conjugation quandle is an algebra whose axioms
are motivated from handlebody-knot theory.
