A subset R of a vector space V (or R n ) is called unimodular (or U-system) if every vector r ∈ R has an integral representation in every basis B βŠ† R. A U-system R is called maximal if one cannot add a non-zero vector not colinear to vectors of R such that the new system is unimodular and spans RR.
