Garden of Eden / Orphan

On 25th January 2017, Steven Eker from CSL, SRI International, California, USA, discovered this orphan which sets a new record for the total number of defined cells to be only 88. Notice this orphan is non-convex.

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
