We study classical M5 brane solutions in the probe limit in the AdS7×S4 spacetime geometry with worldvolume 3-form flux. These solutions describe the holography of codimension-4 defects in the 6d boundary dual N = (0,2) supersymmetric gauge
theories. Starting from some half-BPS solutions which follow stricter BPS conditions,
we find a general 1/16-BPS solution. We show how some of the giant-like M5 brane solutions here may be related to the codimension-2 surface operators in the 4d gauge
theory.
