We discover three nested pairs of weak shocks at roughly 50 kpc, 80 kpc and 130 kpc from the center. The total energy associated with the shocks is $\\sim6\\times10^{61}$ erg, with the central AGN driving a pair of weak shocks every 20-30 Myr with a power $P_{sh}\\approx10^{46}$ erg s$^{-1}$. Based on its morphology and age ($\\sim$30 Myr), the inner cocoon shock is associated with the four equidistant X-ray cavities previously discovered.
