Permutates refers to changes or alterations in the arrangement or order of something, often to produce different variations or outcomes. Antonyms of the word permutates, on the other hand, describe actions that involve keeping things in their fixed or stable state. Some examples include: fixed, unchanged, constant, unvarying, unalterable, static, and stationary. These words imply that no rearrangements or modifications are taking place, and things remain in a state of uniformity or consistency. Antonyms of permutates are useful in contexts where stability and consistency are important, such as in scientific research or mathematical calculations.
