explains why we get such a high dimension. So I am guessing the
underlined algorithm is correct but the way to get a hold of the
points is screwy and until C[1][5]->POINTS relates properly to C[3]
this can't be fixed on SAGE's side.

order seems to be random while , but don't know how to get the point
