Perhaps this isn't the best place to ask, but I'm trying to figure out the proper name for the region that exists in-between two points in higher dimensions. Under certain conditions, n-cube or hypercube would be appropriate, but I'm looking for a more general name.
For example, if the point coordinates are (1,1) and (-1,-1), then the points define a square. The points (-1,1) and (1,-1) define the same region. However, if the point coordinates are (1,1,1) and (-1,-1,-1), then the points define a cube. However, if the points were (1,1,1) and (-1,-1,0), then region defined isn't quite a cube. Same idea applies with more than 3 dimensions.
I ask because I'm trying to name such a space, preferably with 1-2 words instead of a 3+ word phrase.
