A089071: Number of liberties a big eye of size

n

gives in the game of Go.

{ 1, 2, 3, 5, 8, 12, 17, 23, 30, 38, 47, ... }

A 5-space big eye can be almost filled in 4 moves, after which one takes and has a 4-space big eye (5 liberties) left. This gives a total of 4 + 5 moves for the opponent and 1 for oneself, for de facto 8 liberties.
