The original arrangement of the state can be seen in Figure 2. In this arrangement,
successive four bits from right to left is called a nibble, successive four nibbles from right to left is a row. Successive
four bits from top to bottom is a slice, successive four nibbles from top to bottom is a column [40]. Bits
are indexed in the form of xyz, where x is the column index (0 to 3 right-to-left), y is the row index (0 to 3 top-tobottom)
and z is the slice index (0 to 3 right-to-left) within a column. Then the right up corner can be seen as the
origin of the state.
