Garden of Eden / Orphan

On 28th May 2015, Steven Eker from CSL, SRI International, California, USA, discovered this orphan of size 99 which sets a new record for the smallest rectangular bounding box to be 11x9.

Also he published this orphan of size 96 inside a 12x8 bounding box in April 2016.

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
