# The checking can not provide stable result because there is no guarantee that coordinates
# for brics_1 will always be {x1, y1, z1} but not {x2, y2, z2} and
# for brics_42 will always be {x2, y2, z2} but not {x1, y1, z1}.
# The coordinates of brics_1 can be both {x1, y1, z1} and {x2, y2, z2}
# The coordinates of brics_42 can be both {x1, y1, z1} and {x2, y2, z2}
