We analyze the important properties and homomorphic aspects of ComCNSBS. For bisemirings, we propose the ComCNSBS level sets. A complex neutrosophic subset of bisemiring S is represented by the symbol G if and only if each non-empty level set R(p,x), where R is a ComCNSBS of S. We show that homomorphic images of all ComCNSBSs are ComCNSBSs, and homomorphic pre-images of all ComCNSBSs are ComCNSBSs. There are examples given to illustrate our results. 2025 2025 259 277 10.54216/IJNS.250231 https://www.americaspg.com/articleinfo/21/show/3199
