WebbFor rotations, the matrix representation of the exponential coordinates is the 3 by 3 skew symmetric representation of omega-hat times theta. The set of all such matrices is called little so(3). For rigid-body motions, the matrix representation of the exponential coordinates is a 4 by 4 matrix in little se(3), which we learned about in the last video.
