Let Vbe a set of bit strings of length k, i.e., V C {0, l}'. The query graph Q ( V ) is defined as follows: the vertices of Q(V) are the elements of V, and {O,V} is an edge of Q ( V ) if and only if no other W E Vagrees with U in all the positions in which V does. If Vrepresents the set of keys for

## Abstract A graph __G__ is called __rigid__ if the identical mapping __V__(__G__)→__V__(__G__) is the only homomorphism __G__→__G__. In this note we give a simple construction of a rigid oriented graph on every set. © 2002 John Wiley & Sons, Inc. J Graph Theory 39: 108–110, 2002
