Z @ (0, 0) movement routine…
X @ aprox. (2, 2) moves backwards N to (2, 4), then W
D moves N to (4.5, 4) then W to meet X @ (2, 4), pushes X, they catch up with A and continue moving W
Y @ aprox. (-2, -2) moves backwards S to (-2, 4), then E
C moves S to (-4.5, 4), then E to meet Y @ (-2, 4), pushes Y, they catch up with D and continue moving E…
