Equidistant frequency permutation arrays and related constant composition codes
This paper introduces and studies the notion of an equidistant frequency permutation array (EFPA). An EFPA of length n = m, distance d and size v is defined to be a v

On uniquely k-determined permutations
Motivated by a new point of view to study occurrences of consecutive patterns in permutations, we introduce the notion of uniquely k-determined permutations. We give two criteria f...

The number of convex permutominoes
Permutominoes are polyominoes defined by suitable pairs of permutations. In this paper we provide a formula to count the number of convex permutominoes of given perimeter. To this ...
