Permutations Containing and Avoiding 123 and 132 Patterns
received April 5, 1999, revised May 12, 1999, accepted May 19, 1999. We prove that the number of permutations which avoid 132-patterns and have exactly one 123-pattern, equals (n 2)2n 3 , for n 3. We then give a bijection onto the set of permutations which avoid 123-patterns and have exactly one 132-pattern. Finally, we show that the number of permutations which contain exactly one 123-pattern ...
متن کاملNon-overlapping permutation patterns
We show a way to compute, to a high level of precision, the probability that a randomly selected permutation of length n is non-overlapping. As a byproduct, we nd some combinatorial identities that are routine to prove using generating functions, but di cult to prove bijectively.

متن کاملAvoiding Permutation Patterns of Type (2, 1) in Compositions
We classify compositions avoiding a single permutation pattern of type (2, 1) according to Wilfequivalence and give the generating function for each of the Wilf classes. 2000 Mathematics Subject Classification: 05A05, 05A15
متن کاملThe Location of the First Ascent in a 123-avoiding Permutation
It is natural to ask, given a permutation with no three-term ascending subsequence, at what index the first ascent occurs. We shall show, using both a recursion and a bijection, that the number of 123-avoiding permutations at which the first ascent occurs at positions k, k + 1 is given by the k-fold Catalan convolution Cn,k. For 1 k n, Cn,k is also seen to enumerate the number of 123-avoidi...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
