Summary: The reliability measure of networks is crucial for network design and maintenance, and various quantitative indicators have been introduced based on connectivity. Super vertex edge-connectivity and cyclic edge-connectivity are important parameters to assess network robustness and have been extensively studied. This paper presents an alternative method to prove results related to the varietal hypercube and also determines its super restricted connectivity and cyclic edge-connectivity.
