==Which definition of the Euler angles is being employed in this page?==
Absolutely no mention is given as to which (of the 12 possible) definitions of the Euler angles are being employed in this discussion.
I agree. This seems to be using the Tait-Brain (or whatever spelling) convention.
This one here is the standard: https://hepweb.ucsd.edu/ph110b/110b_notes/node36.html . It uses the sequence z-y-z, with notation phi, theta, psi.
We can easily verify that the formulas given on this page are wrong for that standard, by computing omega once from phi,theta,psi and their derivatives, and once from the quaternion q as per the presented formula her, and its derivative dq.
This article is frustrating because it pretends a hands-on appeal ("just pick up the equations and use them for your project") when in fact they are plainly incorrect. I only noticed it when GPT pointed me to where it came up with those inconclusive equations; so you are doing a lot of damage here. I propose we pull this article offline until it is correct and verified to be correct. And since we can verify correctness of algebra, I would suggest we go ahead and do this for all Wikipedia articles that feature any formulas.
