ReplaceRepeated 
repeatedly performs replacements until expr no longer changes.
Details and Options
effectively applies 
repeatedly, until the results it gets no longer change. - It performs one complete pass over the expression using
, then carries out the next pass. - You should be very careful to avoid infinite loops when you use the
operator. The command 
will, for example, lead to an infinite loop. - ReplaceRepeated takes the option MaxIterations, which specifies the maximum number of times it will try to apply the rules you give. The default setting is MaxIterations->65536. With MaxIterations->Infinity there is no limit.
