Here and elsewhere in the Dasagitika words are used in their stem form without declensional endings.
Lalla (Madhyamadhikara, 3-6, 8) gives the same numbers for the revolutions of the planets, and differs only in giving "revolutions of the asterisms" instead of "revolutions of the Earth."
The Suryasiddhanta (I, 29-34) shows slight variations (see Pancasiddhantika, pp. xviii-xix, and Kharegat[1] for the closer relationship of Aryabhata to the old Suryasiddhanta).
Bibhutibhusan Datta,[2] in criticism of the number of revolutions of the planets reported by Alberuni (II, 16-19), remarks that the numbers given for the revolutions of Venus and Mercury really refer to the revolutions of their apsides. It would be more accurate to say "conjunctions."
Alberuni (I, 370, 377) quotes from a book of Brahmagupta's which he calls Critical Research on the Basis of the Canons a number for the civil days according to Aryabhata. This corresponds to the number of sidereal days given above (cf . the number of sidereal days given by Brahmagupta [I, 22]). Compare the figures for the number of revolutions of the planets given by Brahmagupta (1, 15-21) which differ in detail and include figures for the revolutions of the apsides and nodes. Brahmagupta (I, 61)
akrtaryabhatah sighragam induccam patam alpagam svagateh | tithyantagrahananam ghunaksaram tasya samvadah ||
criticizes the numbers given by Aryabhata for the revolutions of the apsis and node of the Moon.[3]
