Figure 3.20:
The collision of a B triad with each of the C gliders almost follows the same sequence as the collision with a single or double B. However, in the C2 collision, the secondary salvo of B's meets the developing D prematurely, placing a T3 instead of a T5 at a critical point, culminating in the release of an A and the formation of an EBar after a longer delay than was experienced in the other two collisions. In the C3 collision, the secondary B salvo is hidden in the fragment which forms part of the evolution.
