Where the article explains it
Covariance sends g and to hg and h , or to the appropriate left/right action fixed by convention.
The passage around this formula
The central mathematical test is simple to state. Apply a common frame transformation h to the physical description. Covariance sends g and to hg and h , or to the appropriate left/right action fixed by convention. A left-invariant distance satisfies
Learn the underlying idea
