The topology of a cubic seki resembles that of a cube. Pressed flat, that's
X -------- O | \ / | | O -- X | | | | | | X -- O | | / \ | O -------- X
Eight corners - the groups - connected by twelve edges - their shared liberties.
Here's one not depending on edges:
Or rather this one?
To increase the number of shared liberties, take the one below (made of the one above) and duplicate its two rows and two columns framing its 2x2 center:
etc., giving
Robert Pauli: I guess nobody can gain anything if he starts - under territory scoring, of course (and under area scoring the gain might be equal). At i = 0 and i = 1 it's even disadvantageous. From i = 2 on, without having a proof, I feel that if both go after the weakest opposing group without touching the second to last liberty between them, nobody will be captured. True?
