Garden of Eden 1 is the first Garden of Eden that was explicitly constructed. It was found by Roger Banks in 1971. Since then many smaller Gardens of Eden have been discovered, including the one that results from simply removing the five rightmost columns from Garden of Eden 1 (the result of which has 193 cells and a bounding box of size 28 × 9).
Garden of Eden 1 is still a Garden of Eden even after its five rightmost columns are removed
