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] and iNoMed improved it to 39 in March 2021.[5] ENORMOUS_NAME and iNoMed constructed a 44P5H2V0 gun on October 30, 2020.[6]
It is currently the only period-5 spaceship to have occurred semi-naturally, having first appeared in a soup found using Charity Engine on April 2, 2022.[7] Using the recipe from this soup, a 24-glider synthesis was found by Goldtiger997 and iNoMed.[8]
