On conditions for invariance of partitions of a special form with respect to ( v , 3)-matrices
Dmitry Alexandrovich Burov · Discrete Mathematics and Applications · 2026
Abstract We describe the indecomposable ( v , 3)-matrices such that the systems of imprimitivity of the translation group of the space V v = {0, 1} v weakly diffused by the operation of modular addition remain invariant under multiplication by such matrices. It is shown that the use of such matrices has a substantial affect on the security of LAX-algorithms.
