In this paper, we show that the cover ideals of Jahangir’s graphs are normal, and also satisfy the (symbolic) (strong) persistence property. In addition, we determine when the unique homogeneous maximal ideal appears in the set of associated primes of powers of the cover ideals of Jahangir’s graphs.
