The instantaneous elementary rotations can be combined to produce a vector. If the coordinate axes have been defined as they were here, this vector will be parallel to the axis around which the original transformation produces rotations. Furthermore, the length of the vector will be the same as the rotation produced around this axis.
The instantaneous elementary rotations around the x-, y-, and z-axes are 8.1966°, 10.1496°, and 13.6159°. Based on the conventions used here to define rotations, all of these instantaneous elementary rotations are in the positive direction. If these elementary rotations are treated as a vector
the length of this vector is 18.8571°, and a corresponding unit vector is
