Ptolemy attests that Macedonian forces captured about 40,000, and that over 23,000 of which Alexander picked out the finest and sent them into Macedonia. Scholars like Dr V. S. Agarwala have equated the Arigaeum or Arigaion of Arrian to Sanskrit name Arjunava which finds mention in Pāṇini's Ganapatha  as well as in the Kasika. If this interpretation of scholars like Dr V. S. Agarwala is correct and the "Arjunava" of the Kashika or Pāṇini's Ganapatha is indeed the "Arigaeum/Arigaion" of Arrian, then the probable origin of the Arjunayanas can possibly be speculated.
According to Ptolemy, Macedonian forces captured around 40,000 individuals, and Alexander selected approximately 23,000 of the most skilled to return to Macedonia. Scholars like Dr V. S. Agarwala have suggested a link between the "Arigaeum" or "Arigaion" described by Arrian and the Sanskrit name "Arjunava," which is mentioned in Pāṇini's Ganapatha and the Kasika. If this interpretation proves accurate, it could help us understand the origins of the Arjunayanas.
