Hyper-dimensional array notation

[1(0)21] = [0]

[2(0)21] = 0]([0])[0

[N(0)21] = 0](...[0]([0])[0]...)[0 (N nested)

0](0)21] = [[0](...[0]([0])[0]...)[0 (a nested)

[1(0)2x] = [[0](0)2x-1]

[N(0)2x] = [[0](...[0]([0](0)2x-1)[0]...)[0](0)2x-1] (N nested)

[[0](0)2x] = [[0](...[0]([0](0)2x-1)[0]...)[0](0)2x-1] (a nested)

[N(0)31] = 0](...[0]([0])2[0]...)2[0 (N nested)

[N(0)x1] = 0](...[0]([0])x-1[0]...)x-1[0 (N nested)
