## Summary

, , , , 

In the field of quantum mechanics, multipartite entanglement plays a crucial role in advancing quantum information processing and computation. Two significant types of entanglement within this realm are Genuinely Multipartite Entanglement (GME) and Absolutely Maximally Entangled (AME). In a recent study by Rahul V and S. Aravinda, a new measure called the GME-AME multipartite entanglement measure was introduced to accurately categorize different types of four-partite entangled states. This measure assigns a non-zero value to GME states and reaches its maximum value only for AME states. By applying this measure to analyze four-partite systems using the operator to state mapping technique, the researchers were able to classify four-partite permutation qutrit states based on their level of multipartite entanglement. Through various examples and analyses, it was demonstrated that the newly proposed measure is robust in accurately characterizing complex quantum systems with multiple interacting particles. This research contributes to our understanding of multipartite entanglement and provides a valuable tool for studying quantum information processing.
