   A variant of the General Poster's problem.   
      
   Discover patterns of consecutive symbols in a stream. The patterns are   
   not known in advance, so this is a statistical anomaly detection   
   problem. The stream consists of mostly random symbols over a known   
   finite alphabet. The expected frequencies/probabilities of the random   
   symbols may be known in advance, or inferred from the stream. The   
   minimum and maximum length of patterns of interest are specified as   
   parameters.
