In mathematics, the Moore determinant is a determinant defined for Hermitian matrices over a quaternion algebra, introduced by Moore (1922).
Because quaterion multiplication does not commute, it is necessary to specify the order in which multiplication occurs.
terms consisting of products of elements of the matrix, and for each term specifies an order for those elements to be multiplied.
Specifically, it separates out cycles of factors
Ties in the length of the cycle are broken by listing the cycle with the smallest
This definition has the property that the Moore determinant of a matrix formed from a suitable collection of vectors of quaternions is zero if and only if the vectors are linearly dependent.
