Some suttas in the Saṃyutta Nikāya have inconsistent numbering.
Concrete example: Ven. Anālayo references SN 35.206 in one of his books. He means to refer to “The Simile of Six Animals” (Chappāṇakopama Sutta) but on SuttaCentral this ID corresponds to “The Interior and What’s Impermanent in the Present” (Ajjhattapaccuppannayadanicca Sutta).
I understand that SuttaCentral’s numbering system is different from some other numbering systems. But the translations cataloged by SC for SN 35.206 are not of the same sutta. The Italian and the Hungarian translations are of the Chappāṇakopama Sutta. By contrast, the Spanish translation and Ven. Sujato’s English translation are of the Ajjhattapaccuppannayadanicca Sutta.
The SC ID for the Chappāṇakopama Sutta is SN 35.247, and Ven. Sujato’s translation is listed under there. But the Italian and the Hungarian translations are missing under this SC ID.
I suspect this to be an unreported issue. If it indeed is, I hope this example helps.
