Deception Island is an island in the South Shetland Islands archipelago, with one of the safest harbours in Antarctica. This island is the caldera of an active volcano, which seriously damaged local scientific stations in 1967 and 1969. The island previously held a whaling station; it is now a tourist destination and scientific outpost, with Argentine and Spanish research bases. While various countries have asserted sovereignty, it is still administered under the Antarctic Treaty System.
== History ==
The first authenticated sighting of Deception Island was by the British sealers William Smith...

I just wrote a resistor-network brute-forcer, which generates circuits where the output resistance is a given function of resistors used to make the circuit.
When you extrude a square, you get two faces for the beginning and end points of the extrusion, and then an additional face for each of the four edges. Likewise, when you extrude a cube, you get two cubes for the beginning and end points of the extrusion, and then an additional cube for each of the six faces.
Since we have accurate projections of 3D shapes in 2D space, I want to see a projection of a 4D shape in 3D space. Obviously can't do that on a computer though
@ETHproductions You can model it on a computer in 3D, then either 3D print it, display it on a 3D monitor, or just rotate it in 3D on the 2D monitor screen
@El'endiaStarman I'm afraid I don't know enough about that universe to get the reference. My childhood was far enough back to be based more in Middle Earth and Narnia...
@ETHproductions If you draw a cube on a 2D surface (paper/screen) then it won't have right angles unless you draw it face on. I guess you'd get that kind of distortion taking 4D to 3D, but since we're used to at least some of that distortion maybe it would be OK.
@trichoplax Probably the time-turner in Prisoner of Azkaban. Anyway, in the Harry Potter universe, people figured out how to make paintings and photographs move.
Basically, printed gifs (in the case of moving photographs).
@El'endiaStarman I spent a long time in Narnia, but fortunately time passes much quicker there, so I returned without losing much time. The same cannot be said of Middle Earth. I lost months there...
@ETHproductions Something about how when you look at some pictures of a cube, you don't see inside it and you don't see what's on the other side, just what's facing you. I think that's how that image works.
@El'endiaStarman I think Colin Creevey mentioned that you have to dip the photographs in a special potion. This may also apply to magically-animated drawings and magically-animated 3D prints
As you progress from unit square, to unit cube, to unit tesseract, and so on to higher dimensions, the centre gets further and further away from the vertices, without limit.
@KritixiLithos I don't really know now to explain it. You can get a cube by joining two squares in the third dimension, and you can get a tesseract by joining two cubes in the fourth dimension.
In geometry the net of a polyhedron is an arrangement of edge-joined polygons in the plane which can be folded (along edges) to become the faces of the polyhedron. Polyhedral nets are a useful aid to the study of polyhedra and solid geometry in general, as they allow for physical models of polyhedra to be constructed from material such as thin cardboard.
An early instance of polyhedral nets appears in the works of Albrecht Dürer.
== Existence and uniqueness ==
Many different nets can exist for a given polyhedron, depending on the choices of which edges are joined and which are separated. Conversely...
all github repos are the same -- filled with millions of files and directories that have absolutely nothing to do with anything other than maintaining the github repo
@TuxCopter how do i find the code base? i've never been able to answer that question when looking at a github repo. all files have like one function in them and that one function is never the function that I'm looking for the source code for. it makes for some very unhelpful browsing.

With 140 bytes or fewer (Twitter counts by characters but for consistency with other questions I'll use bytes), write a function that takes no arguments and returns the largest finite integer you can.
Score is by how large the result is.
