In this paper, we study the symmetry of the nonzero component graph \(\Gamma _n ({\mathbb {F}})\) of an n-dimensional vector space over a field \({\mathbb {F}}\) . We explicitly compute the automorphism group of \(\Gamma _n ({\mathbb {F}})\) and compute stabilizers, orbits, and the determining number of \(\Gamma _n ({\mathbb {F}})\) . We then characterize all the determining sets of \(\Gamma _n ({\mathbb {F}})\) . Using this characterization, we compute the determining polynomial of \(\Gamma _n ({\mathbb {F}})\) when \({\mathbb {F}}\) is a finite field. We also discuss the core property and the Wiener index of \(\Gamma _n ({\mathbb {F}})\) .
