, needing only 109 cells, is the new record-holder for smallest size. Its Garden of Eden 
has 69 on-cells and fits into a 11x11 bounding box. Furthermore this pattern exhibits a quarter-rotation symmetry.
Moreover Nicolay Beluchenko discovered on 23th November 2009 this new record-holding Garden of Eden for minimal number of living cells, 59 on-cells,
,
which also fits into a 11x11 rectangle but its orphan 
is a bit larger needing 113 cells.
As usual the challenge remains: Can you find a smaller one --- i.e. proving that your example has no predecessor in Game of Life and has fewer living cells or
needs a smaller area for residence?
YES
