 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
