Add to ORKGCube, triangles, tetrahedra, inequalities, 2d, 3d, 4dThe permuted inequalities x<y<z, x<z<y, etc. split the unit cube into six congruent right-angled tetrahedra (called "orthoschemes"). In 2D there are two right-angled triangles, corresponding to x<y and y<x; in 4D there are 24 simplices corresponding to w<x<y<z, etcComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Matemátic
