Abstract
Let be a finite group. The group pseudo-algebra of is defined as the multi-set where is the number of irreducible characters of with codegree . We show that there exist two finite -groups with distinct orders that have the same group pseudo-algebra, providing an answer to Question 3.2 in \cite{Moreto2023}. In addition, we also discuss under what hypothesis two -groups with the same group pseudo-algebra will be isomorphic.
