A unimodular matrix is a square integer matrix with a determinant of either +1 or -1. In other words, for a matrix \\( A \\) to be termed unimodular, it must satisfy the condition: \\\[ \\text\{det\}(A) = \\pm 1 \\\] Unimodular matrices have several important properties and applications, particularly in areas such as number theory, algebra, and the study of lattice structures.
