- #C So we could build another sawtooth pattern from this. As in the
- #C first orthogonal sawtooth, we'd need a shotgun to produce salvos
- #C consisting of a HWSS and 2 LWSSs. The period would probably have
- #C to be 120, leading to an expansion factor of 11, the same as for
- #C the sawtooth based on David Bell's p9 c/3. If we could reduce the
- #C period to 60, we could get an expansion factor of 6, the same as for
- #C the diagonal sawtooth. Such a reduction might happen in two ways:
- #C First, your search might find a spark capable of turning a LWSS into
- #C a loaf in the right place, as in David's c/3. Second, if you replace
- #C the HWSS above by a LWSS, it becomes a traffic light; if the LWSS
- #C pair has the right spacing, it might be able to start pulling a loaf
- #C on its own. (The diagonal sawtooth works that way.)
-
- #C (By "expansion factor", I mean this: Suppose a particular event,
- #C such as the creation of a loaf, occurs at times T(0), T(1), T(2), ...
- #C Then the expansion factor is the limit of T(n+1)/T(n) as
- #C n -> infinity. For this type of sawtooth, in which a period p
- #C shotgun fires salvos of speed rc at a spaceship of speed sc, creating
- #C something which gets pulled a distance d by subsequent salvos, the
- #C expansion factor is
-
- #C rsp
- #C 1 + ------.)
