The very long prodigal is a 12-cell still life.
Construction
This still life is known to be constructible with 7 gliders.[1] A 8-glider synthesis was found in April 2019.[2] A 7-glider synthesis was found by Oscar Cunningham in March 2021.[3] Some alternate syntheses can be found in Mark Niemiec's database.[4]
