[4] The Chandaḥśāstra is a work of eight chapters in the late Sūtra style, not fully comprehensible without a commentary.
According to some historians Maharshi Pingala was the brother of Pāṇini, the famous Sanskrit grammarian, considered the first descriptive linguist.
The Chandaḥśāstra presents a formula to generate systematic enumerations of metres, of all possible combinations of light (laghu) and heavy (guru) syllables, for a word of n syllables, using a recursive formula, that results in a partially ordered binary representation.
[13] Pingala's work also includes material related to the Fibonacci numbers, called mātrāmeru.
