@quartata that doesn't make it any more interesting too me. Code-golf is not about who can write the first answer in language with most-built-ins, it's who can abuse quirks and features of the language and use crazy tricks to squeeze out the most bytes.

Likewise, toroidal geometry means that if you move beyond the boundaries of the world, you reappear on the other side (roughly). It seems to me initially that these two geometries are not mutually exclusive, just from the given definitions.

Beta Decay

@MartinEnder It's kind of mapping the coordinates from the trigonal grid (in the input, there will be points plotted on it) to a 3d cartesian grid

Eric Tressler

@El'endiaStarman This isn't my field, but I think that there is no hyperbolic metric on the torus (I think if you "go around" the torus to your starting point, you will find that the metric cannot be both "expanded" as hyperbolic space demands and also the same as when you started)

You could probably attach a hyperbolic third dimension to a flat toroid, though

it makes a difference whether you have Range@5, Range@x or Range@#.

TùxCräftîñg

the parameter of range is a constant

Martin Ender

Although if you have a range the easiest thing is probably to get a larger range and use modulo

e.g. Mod[Range@15,5,1] instead of, say, Table[##&@@Range@5,3]
