In a direct flip, only N, X, H, O and I are the same upside down.
In a flip and rotate, S, E and D are also the same and, depending on the type of font, B and K may also be the same.

SWIMS
I only know that x and o stay the same
The reason there is an upside-down capital M (which resembles a W) but not an upside-down capital W (which does not resemble an M) is due to their symmetrical properties. When flipped vertically, the shape of the M aligns with that of a W, while a W does not have a corresponding shape that resembles an M when flipped. This distinction arises from the specific angles and curves of the letters, making the M the only letter that visually inverts to match another in this way.
The word you are looking for is "SWIMS." When flipped upside down and viewed in a mirror, it still appears the same. This unique characteristic makes it a fascinating example of an ambigram.
The word is NOON.
They are also letters upside down: y n u o s x and z Comment: Don't think that's it. Y is not an upside-down h. If this is it, c and l are missing from the set, and you'd have to allow p as an upside-down b. Besides, the answer could involve the capital letters instead.
The word SWIMS, when written in upper case letters, is the longest word in the English language that reads the same both forward and upside-down with no reading difficulty.
For All.
