The order of illions refers to the naming convention for large numbers based on powers of a thousand. It starts with a million (10^6), followed by a billion (10^9), trillion (10^12), quadrillion (10^15), quintillion (10^18), and continues with sextillion (10^21), septillion (10^24), octillion (10^27), nonillion (10^30), and decillion (10^33). Each subsequent term increases by a factor of one thousand. This pattern extends to larger numbers using prefixes based on Latin and Greek roots.
