Hi all, I have a simple question regarding the function. I have the following code $p = new Polytope(POINTS=>[[1,1,1],[1,1,0]]); print $p->FACES; The result prints: 0 0 1 1 0 -1 It stands for 1\geq x_2 , x_2 \geq 0 . Yet, where is the condition x_1=1 ? I was hoping to get -1 1 0 1 -1 0 0 0 1 1 0 -1 ...
