  1. #Life 1.05
  2. #D Orthogonal sawtooth with expansion factor 11
  3. #D Population is unbounded but does not tend to infinity.  Its graph is a
  4. #D sawtooth function with ever-increasing teeth.  More specifically, the
  5. #D population in generation t = 36*11^n - 37 (n>=1), is 7(t+1)/30 + 746, but the
  6. #D population in generation 12*11^n - 51 (n>=1) is only 635 if n is even, 633 if
  7. #D n is odd.  This uses a spark from a period 9, speed c/3 orthogonal spaceship,
  8. #D found by David Bell, to turn a LWSS into a loaf, which is then pulled back by
  9. #D pairs of LWSSs.  When the loaf is pulled all the way back, it gets deleted and
  10. #D the cycle begins again.  (The deletion is caused by interaction with a LWSS
  11. #D and with 3 gliders which would otherwise form a LWSS.)
  12. #D
  13. #D Try putting something in the path of the c/3, far away from the guns.  When
  14. #D the beam of LWSSs hits the resulting garbage, it is likely that a loaf will
  15. #D eventually be formed and pulled back.  No matter where the loaf starts, when
  16. #D it reaches the guns it will be deleted by one of 3 different reactions.  (The
  17. #D block behind the c/3 is used for one of these; it's not needed for the
  18. #D sawtooth pattern itself.) The beam of LWSSs will again be released and may
  19. #D eventually form another loaf.  The process may be repeated many times until
  20. #D either the LWSS beam burns through the garbage or the reaction moves upstream
  21. #D and consumes the guns.
