Which translation of Mūlamadhyamakakārikā 25:19-20 is mentioned in Wikipedia?

Wikipedia mentions the following translation of Nāgārjuna's Mūlamadhyamakakārikā 25:19-20 without mentioning a source: > There is nothing whatsoever of samsara distinguishing (it) from nirvana. There is nothing whatsoever of nirvana distinguishing it from samsara. (That?) is the limit which is the limit of nirvana and the limit of samsara; Even a very subtle interval is not found of (between) them.[citation needed] Where does that translation originate from?
