44P5H2V0
44P5H2V0 is an unnamed 2c/5 orthogonal spaceship discovered by Dean Hickerson on July 23, 1991,[1] being the first 2c/5 spaceship to be found. Robert Wainwright and David Bell then found some small tagalongs that allowed the creation of arbitrarily large 2c/5 spaceships. These were the only known 2c/5 spaceships until the discovery of 70P5H2V0 by Hartmut Holzwart on December 5, 1992.[2]

Goldtiger997 found a 131-glider synthesis for 44P5H2V0 on August 29, 2020.[3] Tanner Jacobi improved the synthesis to 41 gliders the same day.[4]

gollark: It seems like AMD could have done a much better job than they did, though.
gollark: DRAM is what regular RAM sticks use: it uses a lot of capacitors to store data, which is cheap but high-latency to do anything with, and requires refreshing constantly. SRAM is just a bunch of transistors arranged to store data: it is very fast and low-power, but expensive because you need much more room for all the transistors.
gollark: They say they have 200 MB of SRAM on each (16nm) chip. That sounds hilariously expensive.
gollark: It's cool that they have a Vulkan-based version instead of just supporting CUDA only.
gollark: Swap on TPU *when*?
