On Yuan Chwang's Travels in India, 629–645 A.D. v2.c18.21

v2.c18.21

Near this monolith, the narrative tells us, was a tope to mark the place where Ājñāta Kauṇḍinya and his four companions settled in order to apply themselves to devotional meditation. These men had been practising austerities with the P'usa elsewhere; and when they saw him give up the practice, they left him, and came to this place. The tope beside this marked the place where 500 Pratyeka Buddhas "entered nirvāṇa" at the same time; and there were three topes at the sitting places and exercise-walks of the Three Past Buddhas.
