R64 is an elementary conduit, one of the original sixteen Herschel conduits, discovered by Dave Buckingham on September 26, 1995.[1] After 64 ticks, it produces a Herschel rotated 90 degrees clockwise at (11, 9) relative to the input. Its recovery time is 153 ticks. This can be improved to 61 ticks by adding a from-the-side 7×9 eater inside the turn, as shown in the infobox to avoid interference from the output Herschel's first natural glider, and further reduced to 57 ticks with an eater 1 (in the ghost position) to remove the temporary first natural block. In the pattern shown in the infobox, a ghost Herschel marks the output location.
R64 is the first known stable conduit, and one of the three known Blockic (and consequently Spartan) conduits. It was inspired from Mark Niemiec's early investigation of common methuselahs in 1973, where he observed that a new B-heptomino, turned 90 degrees, arises from the evolution of a B-heptomino at generation 64 along with the first natural glider and some other debris. Before the p1 conduit, Dave Buckingham found three periodic versions employing copies of Kok's galaxy, figure eight, mazing and blocker in 1991:
