Let X = {(x, y)∈ℝ2: x2 + y2 = 1} ∪ ([-1, 1] * {0}) ∪ ({0} * [-1, 1]). Let n0 = max{k: k < ∞, there are k distinct points p1,..., pk ∈ X such that X∖{p1,..., pk}is connected}Let q1,¦,qn0+1 be n0+1 distinct points and Y = X\{q1,¦,qn0+1}. Let m be the number of connected components of Y. The maximum possible value of m is ______
