Garden of Eden / Orphan

On 14st December 2011, Marijn Heule, Christiaan Hartman, Kees Kwekkeboom and Alain Noels from the TU Delft, The Netherlands, improved the record for the fewest number of cells of any known Garden of Eden configuration by constructing this quarter-rotational symmetric orphan . It has 56 living cells and a total of 92 cells. Moreover it sets a new record for smallest bounding box by fitting into a 10x10 box.

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 fewer total number of cells as any orphan?YES
