I'm trying to find a word or phrase for the picture we get when we put everything that is on the right side to the left and every thing that is placed on the left side to the right, while preserving the order in the opposite manner. I mean if we have: pen, pencil, ruler, needle; after reordering we have: needle, ruler, pencil, pen. Or if you have an image, it must be transformed into what you see in the mirror. Or if you have a kettle with its handle on the left side; now after the transformation the handle is on the right side (and actually with reversed image).
By searching the internet I found the words and phrases: Reversed output, mirror output, mirror reflection of the output, reversed output, mirror reversed output. (One more question in parenthesis: Do we have mirrorly reflected output? Are we able to add -ly to mirror to use it as an adverb at all?)
What is the correct and appropriate word for it? I know that if it was just about a string of characters I could use reversed output. But now I have two dimensional objects (like matrices).
As for its part of speech, I want to use the word/phrase as an object, not a verb.
