Four-dimensional vectors used in special relativity are elements of a non-Euclidean point space because the scalar product of a vector by itself may be negative.

Note 1 to entry: The usual geometrical three-dimensional space is a Euclidean point space. Four-dimensional vectors used in special relativity are elements of a non-Euclidean point space because the scalar product of a vector by itself may be negative. Another example of non-Euclidean vector space is the set of *n-*bit words formed of the digits zero and one with addition modulo two, because the scalar product of a vector by itself can be zero for a non-zero vector.
