Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun Any of a set of objects resulting from the generalization of a two-dimensional circle and a three-dimensional sphere to n dimensions. In n-dimensional space, a hypersphere is the set of all points that are a given distance, called the radius, from a given point, called the center.
from The Century Dictionary.
- noun Equidistantial surface.
- noun In four-dimensional space, the three-dimensional quadric spaces through the intersection of X5 = 0 and where is a three-dimensional space which is met by any line of S4 in two points.

- noun A mathematical object existing in more than three dimensions, analogous to the sphere in that all points on the surface are equidistant from the central point; a generalization of a sphere in more than three dimensions.
