[math-fun] large numbers in ancient India

Do any of you know about the numbers discussed in the "Ancient India" section of https://en.wikipedia.org/wiki/History_of_large_numbers, or with the book by Georges Ifrah on which it is based? I'm puzzled by *lalitavistarautra *and the succeeding entries, whose definitions refer to "infinities". If the word is being used in its strict mathematical sense, then *lalitavistarautra* et al. cannot be identified with specific positive integers. But perhaps the translator (and/or the creator of this wiki page) erred? Perhaps the word translated as "infinities" is obscure in its meaning but can be assumed from context to have been intended to denote some specific large number? I'd be eager for information on this.
