This is a 3D multiplication table.

3D Multiplication X * Y * Z

I took a 3D array and added header fields. You take the five sets and stack them in order. You get 0 to 3 on X,Y and Z axis. The tables create a 3D multiplication cube.

//create a multiplication table for 0 to 5
class Program
{
static void Main(string[] args)
{
int z1 = 5;
int z2 = 5;
int z3 = 5;

int[,,] array = new int[z1, z2, z3];
int x;
int y;
int z;
int s;

//generate the X,Y, and Z rows
for (x = 1; x < z1; x++)
{
array[x, 0, 0] = x - 1;
};
for (y = 1; y < z2; y++)
{
array[0, y, 0] = y - 1;
}
for (z = 1; z < z3; z++)
{
array[0, 0, z] = z - 1;
}

//Calculate the table
// (0, 0, 0) should be 0 in corner

// Start of each count is
// (1, 0, 0) is X at 0
// (0, 1, 0) is Y at 0
// (0, 0, 1) is Z at 0

for (x = 1; x < z1; x++)
{
for (y = 1; y < z2; y++)
{
for (z=1; z < z3; z++)
{
array[x, y, z] = (array[0, 0, z] * array[0, y, 0] * array[x, 0, 0]);
}
}
}

s = array[2, 2, 2];
Console.WriteLine(s.ToString("000") + " ");
Console.WriteLine();

s = array[3, 3, 1];
Console.WriteLine(s.ToString("000") + " ");
Console.WriteLine();

//prints the array
for (x = 0; x < z1; x++)
{
for (y = 0; y < z2; y++)
{

for (z = 0; z < z3; z++)

Set 1: Red top column and first row, are X and Y values 0 to 3. Cut each of the 5 arrays and place in order on top of each other it forms a 3D multiplication table from 0 to 3. Starting second array to fifth array, left upper corner is Z = 0 to 3. Second column and second row starts at 0. Last column and row = 3. Top row and first column are just Z values on sets 2 to 5. It forms a cube with header rows and columns.

Red 27 is 3 x 3 x 3. X, Y and Z axis goes 0 to 3 with headers.
