Recently,
Brenti and Carnevale introduced an odd
analogue of the classical permutation diagram.
This gives rise to odd analogues of other
permutation aspects such as length and inversions.
Unlike in the classical setting, multiple
permutations might have the same odd diagram.
This prompts the study of "odd diagram classes":
sets of permutations having the same
odd diagram. We will discuss the rich combinatorial
structure of these classes, including
connections to pattern avoiding permutations
and the Bruhat order. This is joint work with
Francesco Brenti and Angela Carnevale.\n\n
