We have investigated the vortex state in a superconducting dice
network using the Bitter decoration technique at several magnetic
frustrations 
and 1/3. In contrast to
other regular network geometries where the existence of a commensurate
state was previouly demonstrated, no ordered state was observed in
the dice network at f=1/2 and the observed vortex-vortex correlation
length is close to one lattice cell.
