about PATTERNS

In[1]:= str = "1223322176644667983323456554";

In[2]:= StringCases[str, a_ ~~ b_ ~~ b_ ~~ c_ /; a != b != c]

Out[2]= {1223, 3221, 7664, 4667, 8332, 6554}

  the above code will extract the pattern  abbc  from the above string, but 
how i could put a rule to just display the substrings wich match this 
pattern and also have an inverted form in the main string so the output will 
give the following:

Out[2]= {1223, 3221, 7664, 4667}

thanks
