Garden of Eden / Orphan

On 30th November 2009, Nicolay Beluchenko from Russia improved again the record for the fewest number of living cells of any known Garden of Eden configuration by constructing this nearly totally diagonal-reflection symmetric pattern . It has 49 living cells and its corresponding orphan consists of 110 cells.

On the same day he found a new record holder for minimal density of living cells of any known orphan which has 58 living cells but needs a total of 139 cells which corresponds to on-cell density of about 0.417.

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
