It seems like you might be referring to a specific context or study, possibly within the realms of mathematics, physics, or perhaps a specific system of dynamics. However, the terms "258" and "11" without more information make it difficult to discern exactly what you're asking about.
If you could provide more context about what you mean by "the first change of Dynamics," as well as what "258" and "11" refer to, I would be better equipped to assist you.
