We present results from the deep Chandra observation ( 105 ksec ) , together with new Giant Metrewave Radio Telescope and Very Large Array data of the AGN outburst in the radio-loud galaxy group 3C 88 .
The system shows a prominent X-ray cavity on the eastern side with a diameter of \sim 50 kpc at \sim 28 kpc from the nucleus .
The total enthalpy of the cavity is 3.8 \times 10 ^ { 58 } erg and the average power required to inflate the X-ray bubble is \sim 2.0 \times 10 ^ { 43 } erg s ^ { -1 } .
From surface brightness profiles we detect a shock with a Mach number of M = 1.4 \pm 0.2 , consistent with the value obtained from temperature jump .
The shock energy is estimated to be 1.9 \times 10 ^ { 59 } erg .
The size and total enthalpy of the cavity in 3C 88 are the largest known in galaxy groups , as well as the shock energy .
The eastern X-ray cavity is not aligned with the radio jet axis .
This factor , combined with the radio morphology , strongly suggests jet reorientation in the last tens of million years .
The bright rim and arm features surrounding the cavity show metallicity enhancement , suggesting they originated as high metallicity gas from the group center , lifted by the rising X-ray bubbles .
Our Chandra study of 3C 88 also reveals that galaxy groups with powerful radio AGN can have high cavity power , although deep X-ray observations are typically required to confirm the cavities in galaxy groups .
