surface, assuming that the gluing is performed in the 3D space, rather than through some topological magic (sorry, I am not an expert in this field and lack the right terminology; my judgements are restricted to common sense intuition). Note that the article about the umbilic torus doesn't establish any relation of it with the Möbius strip (the link in the "See also" section doesn't count as such). I think that the misleading sentence has to be either removed or reformulated in a less confusing way and a more detailed explanation can be provided in the article about umbilic torus.

1405:. My feeling was that something was wrong with it. A Möbius strip is single-sided whereas the Umbilic torus apparently has inside and outside. Now thinking about it more carefully, I guess that I found the flaw in your reasoning. The fact that the boundary goes three times around the center of the torus doesn't mean that the strip makes three half-twists. Actually it only makes a full twist (two half-twists). Hence it is not topologically equivalent to a Möbius strip.

the main point of a movie about this character, then maybe it could be listed among other fictional works with Möbius-strip plotlines. Or if your links' theory that this is another example of the bullshit "Möbius strips are things we don't understand therefore they could cause time loops" trope turns out to be validated, then maybe it could be mentioned, briefly, in the sentence with three examples of this trope. But the current

to which the idea of a Möbius strip has had a significant influence (fine art, design, literature, etc). A name of a character in a movie franchise is not a significant influence to a wide area of popular culture. We already have plenty of examples of movies where the strip plays a much more significant role in the overall structure of the movie and not just in the names or behavior of one its characters. —

couldn't find anything, which is a crude way of going about things, but I'd find it highly unlikely that someone would evaluate the area analytically and not put a numerical value to it. So I suspect it's not been properly investigated, and I doubt there's a closed form. For posterity, the integral is
1382:
You are confusing the standard embedding of the Möbius strip (with one half-twist) with the Möbius strip itself (a topological surface independent of how it is embedded into space). If you perform any odd number of half-twists to a strip before gluing it back to itself, you get a Möbius strip, with a

The popular culture section is not intended as a catch-all listing of anything vaguely related (go to tvtropes for that sort of thing), but as an organized survey of different wide areas of popular culture

I'm leaning towards no. If the connection is only to the misspelled name "Mobius", no. If we have in-depth published reliable sources specifically connecting this character's plot line to the Möbius strip itself, and not just fan speculation which some of your sources look like, and this plot line is
1366:
The link to "Umbilic torus" in the "See also" section is accompanied with a claim that the
Umbilic torus can be obtained from a Möbius strip by gluing the latter along its single edge. IMHO, that statement is false, at least in regular 3D space, where the result would have to be a self-intersecting

Interesting. Numerically (from their formula) it's ≈6.62715 for a fairly natural choice of dimensions, namely a strip width of 1 unit rotating while following a circle of radius 1, indeed slightly greater than Pappus's theorem's estimate of 2π. I searched for that constant (and approximations) and

different embedding for each different number of half-twists (see the second paragraph of the lead). The umbilic torus has a boundary that, if you cut along the ridges, is a Möbius strip. It is a Möbius strip embedded with three half-twists rather than one, but that is still a Möbius strip. —
1419:
Ok, this time I think you may be correct. If it really were a Möbius strip then (regardless of number of twists) traveling around the boundary (without crossing any ridges) until you return to your start should take you to the inside, but it doesn't.
617:
Wouldn't that create two Möbius strips instead? Explanation caption for the image lists that it creates a Möbius strip with two tracks, and one non Möbius strip. In reality, this should create a two tracked Möbius strip and a separate Möbius strip.

It might be interesting to say what the area of the surface swept by a rotating line segment is. I don't know the answer, but I found a reference saying what the area isn't: it isn't what you would get by trying to apply

As for ALT1 below. Aion is NOT holding a Möbius strip. Give me a break and take a better look. It is just a strip and the Romans perished (due to lead poisoning) before even inventing zero.
