![Violet chooses four points D, E, F, G in R³, and decides to tell Luna some of the coordinates. However, Violet decides to withhold two of the coordinate
values, and labels them x and z instead. Violet shows Luna the following list:
D= (3,1,0),
E3 (2,5, г).
F = (x, 6, –3),
G = (4,0,1).
Violet also says to Luna, "The points D, E, F, G are the vertices of a parallelogram, though I won't tell you the order of its vertex labelling."
