... locally restricted since parts arbitrarily far apart must be equal. Nevertheless, we can apply our methods to the study of the set of palindromes in a collection of regular, locally restricted ... (2009), #R108 6 11 Palindromes For locally restricted palindromes, we assume that Φ is invariant under reversal, obtaining results as for regular locally restricted compositions. In this cas...
