Once we publish the Levi-Civita image for a determinant like we did above, the absolutely antisymmetric residence that it possess gets apparent: swapping any two indices corresponds to interchanging their corresponding rows inside the matrix as a result of which the determinant, that's the Levi-Civita alone, adjustments indicator.
The significance of Levi-Civita Attributes in four dimensions lies in their role from the mathematical description of 4-dimensional Areas, which have vital purposes in physics and cosmology. They even have purposes in other fields such as Computer system graphics and robotics.
