#GLF 1.0
#D All 8 of David Buckingham's Herschel conduits demonstrated.
#D
#D A Herschel is the 20th generation of the B-heptomino. Various
#D combinations of still life can be made to assist the forward
#D propagation of a Herschel, and with Buckingham's complete set,
#D a glider gun of any period greater than 61 can be constructed.
#D This period-1246 loop demonstrates all of them. Each conduit in
#D this pattern is boxed off and labeled, and future Herschel
#D positions are marked by ghost Herschels.
