saptarṣayastadā prāṃśu pradīptenāgninā samāḥ.
saptaviṃśati bhāvyānāṃ āndhrāṇāntu yadā punaḥ .. 273.38

*The Seven Ṛiṣis were then (at the time of the birth of Parikṣit) on a line with the towering brilliant Agni (the presiding deity of Krittika) At the end of the future twenty seven Andhras the cycle repeats itself* (Pargiter)

Note.—Mr Pargiter, reads "saptarṣayās tadā Pusye Pratīpe rajñi vai samam and he translates it thus:—The Great Bear was situated equally with regard to the lunar constellation Puṣyā while Pratīpa was king At the end of the Andhras, who will be in the 27th century afterwards, the cycle repeats itself
