% Domain   : Geometry (Oriented curves)
% Problem  : Open curve betweenness property for three points
% Version  : [EHK99] axioms.
% English  : If P, Q and R are points on an open curve c then Q is not between
%            P and R wrt. c, iff P is between R and Q wrt. c or R is between
%            Q and P wrt. c or at least two of the points are identical.
