Abstract:
A symmetric graph  is said to be a pseudocover of its imprimitive quotient  if they have the same valency and the original graph is not a cover of its quotient We provide a criterion for a symmetric graph being a pseudocover of its quotient. 
Some related results for pseudocovers of complete graphs and tetravalent graphs will be given.
