    55This problem might be too difficult for the owl code to solve since it would require much extra complexity to sometimes count topologically false eyes as real ones. It should be feasible to read it correctly with an invincibility reader, however, which should preclude the owl analysis.

     7More simple example : On a 9x9 board the # group is alive with 2 topological false eyes, which connect twice the whole dragon.
