"Early research showed that number combinations beginning with the numeral 0 (e.g., 0136.com, 0591.com) were the least desired, followed by numbers that contained the numeral 4. Apparently, “4" has negative meanings in various non-Western cultures. For example, in Ancient Hebrew and Chaldean philosophies, the number 4 is associated with mortality and death. Also, the Chinese people try to avoid the number 4 because it sounds the same as death in Cantonese. The numbers most in demand by domain owners were those with repeating numbers, those representing special historical dates, and those with numbers 3, 6, and 8. Again, this preference for certain numbers over others seems to be rooted in ancient numerology - where cultures believe that the universe is based on mathematical principles."
