| Nov 12, 2020 at 12:58 | comment | added | Valter Moretti | The matrix you wrote transforms the column vector $(1,0,0,0)^t$ to $X$. The matrix you are looking for is the inverse of the one you wrote. It transforms $X$ to the temporal unit vector of another reference frame. | |
| Nov 12, 2020 at 12:11 | comment | added | Ansonī Bōdo | I agree with you and found that after the first rotation one needs a boost of velocity $v = -\frac{pc}{a}$ in the z-direction to get the job done. However, I'm still curious about the more algebraic proof outlined in my post. | |
