DESCRIPTION:The entangling power of a unitary operator measures how much e
 ntanglement it generates when acting on random product states. I study the
  time-averaged entangling power for the time-evolution operator of spin-ch
 ain Hamiltonians and find that larger symmetry groups systematically suppr
 ess entanglement generation\, with sharp dips at U(1)\, U(1)xU(1) as well 
 as the SU(2) Heisenberg point\, which persists and sharpens for longer cha
 ins. Integrability leaves its own distinct fingerprints at special points 
 in parameter space. The results suggest that entangling power could serve 
 as a new diagnostic tool for hidden symmetries in quantum many-body system
