The Participle in kta has acute accent (udātta) on the final when it is preceded by su or by a word with which the second member is compared.,
Thus सुकृत꣡म्, सुभुक्त꣡म्, सुपीत꣡म् ॥ With Upamana words we have - वृकावलुप्त꣡म्, शशलुत꣡म् , सिंहविनर्दित꣡म् ॥ This debars 6.2.49 and 6.2.48. When सु is not a Gati, the rule does not apply, as सुस्तुत꣡म् भवता ॥,
