Cloverleaf interchange (or fourfold racetrack-weld-racetrack) is a 56-cell still life exhibiting D8_1 symmetry.
A natural occurrence was found in the ash of a random asymmetric soup by Adam P. Goucher on August 12, 2016.[1][2] This makes it the largest known still life to occur completely naturally, surpassing the previous record holder, the 46-cell professor; it had previously arisen semi-naturally in various higher symmetries, including C2_1, C4_1, D2_+1, D4_+1, D4_+2 and D4_x1.
'BlinkerSpawn' found a 12-glider synthesis on the same day.[3] GUYTU6J improved this to 10 gliders on February 5, 2020.[4]
A cloverleaf interchange can be hassled by Carnival shuttles, like this:
