Garden of Eden 6 is a Garden of Eden, previously the smallest known Garden of Eden. It surpassed Garden of Eden 5, which had been the smallest known Garden of Eden for two years. The orphan on which it is based was also the smallest of its kind, requiring only 92 cells to specify. It is one of few known Gardens of Eden that is rotationally symmetric, and it was found by Marijn Heule, Christiaan Hartman, Kees Kwekkeboom, and Alain Noels, using a SAT-solver based approach.
