The bumper is a type of colorpreserving periodic reflector with a repeat time of 34 that was discovered by Tanner Jacobi on April 6, 2016. It consists of a transparent loaf, an eater, and a sparker. It can use sparkers of any period above period 3. The discovery of the bumper allowed many gun periods in the gun collection to be significantly reduced in terms of bounding box.

In the news



Did you know...

 ... that loafer is the fifth smallest nonflotilla spaceship, but was discovered 43 years after the four spaceships smaller than it?
 ... that despite being the fourth smallest nonflotilla orthogonal spaceship, loafer did not appear from a single randomly generated soup until 2020?
 ... that all known glider eaters take at least four ticks to recover to their original state after eating a glider?
 ... that among Lifelike (outertotalistic) rules, Conway's Life's "near neighbours" B35/S23, B36/S23, and B38/S23 are not explosive, but B37/S23 is?
 ... that there is roughly one chance in 10^(N/3) that a still life appearing out of random soup will have a population of exactly N cells?
 ... that the number of still lifes with N+1 bits is roughly 2.48 times larger than the number of Nbit still lifes?
 ... that the odds of a randomlychosen 20 × 20 soup pattern being a methuselah that lasts between N and N + 1000 ticks, are roughly the same as the odds that it will last any amount of time longer than N + 1000 ticks?
 ... that all still lifes up to 17 cells can be synthesized at a cost of less than one glider per cell?
 ... that the first elementary knightship, Sir Robin, was discovered only in 2018, with there having been a very close call in 2004?
 ... that there is a 5 × 2 counterexample to the Coolout Conjecture, proving that patterns that are internally compatible with stability can not always be made part of a larger still life, no matter what cells are added around the edges?
