A sawtooth using a convoy of c/3 ships and puffers.
A period 24 c/3 puffer lays down a line of blocks.  A HWSS travels up
the row of blocks deleting them.  When the HWSS reaches the puffer,
it is converted into a glider.  The glider reacts with a "big-spark"
created by period 45 puffers to create a LWSS.  The LWSS travels back
in the opposite direction of the HWSS.  It reaches a period 120 HWSS gun
whose output is normally suppressed.  The LWSS is destroyed causing one
HWSS is released from the gun to start the cycle.  Meanwhile, the c/3
convoy has moved further away and a larger number of blocks has been laid.
