In mathematics, a logical matrix may be described as d-disjunct and/or d-separable. These concepts play a pivotal role in the mathematical area of non-adaptive group testing. In the mathematical literature, d-disjunct matrices may also be called super-imposed codes or d-cover-free families. According to Chen and Hwang (2006), * A matrix is said to be d-separable if no two sets of d columns have the same boolean sum. * A matrix is said to be -separable (that's d with an overline) if no two sets of d-or-fewer columns have the same boolean sum. * A matrix is said to be d-disjunct if no set of d columns has a boolean sum which is a superset of any other single column. The following relationships are "well-known": * Every -separable matrix is also -disjunct. * Every -disjunct matrix is also -separable. * Every -separable matrix is also -separable (by definition). (Wikipedia).

In this video, I define the notion of adjugate matrix and use it to calculate A-1 using determinants. This is again beautiful in theory, but inefficient in examples. Adjugate matrix example: https://youtu.be/OFykHi0idnQ Check out my Determinants Playlist: https://www.youtube.com/playlist
