nA - F collisions

**Figure 3.13:** There are six different alignments for an A glider approaching an F; they also serve as points of reference for A complexes and D's.

Table 3.9: A single isolated A will transmute an F into an EBar. However, if a second A arrives before the reaction is complete, the results could be quite different. In any event, once the F has changed, any subsequent collider would have to deal with the EBar.

**Figure 3.14:** A single A glider can strike an F with any alignment to create an EBar glider, which is faster. Note that in many cases an isolated T10 presages the EBar's emergence some twenty generations later on, starting out by producing a T5 - T6 pair.

**Figure 3.15:** A tetrad of A gliders can strike an F to produce either C3's or D1's.

**Figure 3.16:** A pentad of A gliders can strike an F to produce C2's no matter what.
