The phrase "a rotation at a" is correct and usable in written English.
It can be used in contexts related to mathematics, physics, or any field discussing movement or transformation around a specific point or axis.
Example: "In geometry, a rotation at a point can change the orientation of a shape without altering its size."
Alternatives: "a rotation around a" or "a rotation about a".
