Function get_plane_vector 

pub fn get_plane_vector(z: usize, t: usize, q: usize) -> Vec<usize>

Get the plane (layer) vector for a given z

Converts z to base-q representation, giving the z_y value for each y-section. This is used to identify “red” (unpaired) vertices in each layer.

The representation stores most significant digit at index 0:

• z_vec[0] = coefficient for q^(t-1) (MSB)
• z_vec[t-1] = coefficient for q^0 (LSB)

Arguments

• z - Layer index
• t - Number of y-sections
• q - Base (coupling factor)

Returns

Vector where element y contains the coefficient for q^(t-1-y)
