Each passing Herschel shifts its block chain forward by 9 ticks. 9 is relatively prime to 31, so a series of glider-suppressing "rephaser" units can shift the block chains by any required distance. This means that a rake unit following on the same block chains can be adjusted to output gliders on any desired lane. So arbitrary [[slow salvo]] recipes can be fired from the rakes, enabling a 31c/240 spaceship to construct its own support by sending LWSS and MWSS spaceships forward to collide with gliders at the front end, and extend the block chains ahead of the ship. | Each passing Herschel shifts its block chain forward by 9 ticks. 9 is relatively prime to 31, so a series of glider-suppressing "rephaser" units can shift the block chains by any required distance.

31c/240 orthogonal is an orthogonal speed equal to thirty one two-hundred-fortieths of the speed of light. A reburnable glider-emitting wick traveling at 31c/240, based on pairs of Herschels traveling along chains of blocks, was discovered in April 2013.[1] Spaceships can be constructed with many mutually-supporting copies of this reaction, somewhat along the lines of the chains of pi climbers in the original Caterpillar.
However, single pi climbers do not emit gliders, whereas Herschel-pair climbers send out a glider to each side every 240 ticks. This is even more prolific than the base reaction used in the waterbear. Therefore, the first step in constructing a spaceship was to find a way to allow Herschel pairs to climb block chains while suppressing all output gliders. In January 2014, Kiho Park suggested a workable suppression mechanism.[2]
Each passing Herschel shifts its block chain forward by 9 ticks. 9 is relatively prime to 31, so a series of glider-suppressing "rephaser" units can shift the block chains by any required distance. This means that a rake unit following on the same block chains can be adjusted to output gliders on any desired lane. So arbitrary slow salvo recipes can be fired from the rakes, enabling a 31c/240 spaceship to construct its own support by sending LWSS and MWSS spaceships forward to collide with gliders at the front end, and extend the block chains ahead of the ship.
31c/240 had been the slowest speed achieved by orthogonal spaceships until March 5, 2016, when 28P10H1V0 was discovered.
