A period 80 sideways rocket puffer.
At the front is a period 40 eater puffer.  Its output is thinned and
converted by a rocket to make a period 80 p16 puffer.  A pair of
rockets then converts the output into a period 80 eater puffer.
Finally a convoy of rockets converts the eaters into sideways rockets.

David I. Bell, January, 1999
