#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.
