The number[1] one (or 1) is not counted as a numerable number, because the numerable number is that integer which increases by squaring. But square of 1 is only 1. Hence, the numerable number (integer) starts with two (or 2).
The Saṃkhyāta numbers (integers) are further classified into three categories:
1. Jaghanya Saṃkhyāta (J. S.) - Minimum numerable number.
2. Madhyama Saṃkhyāta (M. S.) - Middle numerable number.
3. Utkṛṣṭa Saṃkhyāta (U. S.) - Maximum numerable number.
The minimum numerable number is two (2).
The middle numerable numbers are three (3) upto 'maximum numerable number' minus one - (U. S.-1).
Now we consider the maximum numerable number
