#Life 1.05
#D All 8 of David Buckingham's Herschel conduits demonstrated.
#D
#D A Herschel is the 20th generation of the B-heptomino (see BHEPTO).
#D Various combinations of still life can be made to assist the
#D forward propagation of a Herschel, and with Buckingham's complete
#D set, 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. See also SLR, GUNB256.

#D Gens Type Tightest Compression; Notes
#D ---- ---- ---------------------------
#D 64 90 degree 153 (also 73, 74, 77); 1 glider, aimed inward.
#D 77 move+flip 61; 1 glider (natural b-heptomino glider).
#D 112 90 degree 61; 1 glider, aimed outward.
#D 117 move 63; 1 glider. Can be perturbed by single-spark oscs.
#D 119 move+flip 231; 3 gliders.
#D 156 90 degree 62; 2 gliders: Normal B-hepto glider + one more.
#D 158 move+flip 176 (also 101, 102, 109, 111, 159); 1 glider.
#D 190 90 degree 107; 1 glider, aimed inward.
