Pattern Popularity in 132-Avoiding Permutations
The popularity of a pattern p is the total number of copies of p within all permutations of a set. We address popularity in the set of 132-avoidng permutations. Bona showed that in this set, all other non-monotone length-3 patterns are equipopular, and proved equipopularity relations between some le...
