What Is the Original Number of The Beast?

The actual Number of The Beast is only mentioned in Revelation 13:18 ; In the Greek manuscripts, the number is rendered as **χξϛ** or "six hundred and sixty-six". In 2005 Oxford University's Ashmolean Museum revealed the discovery of the oldest manuscript (about 1,700 years old) of Revelation 13 which gave The Beast's number as 616 **χιϛ**. What is the more common belief between the two? What are some examples of Churches that belief in 666 and some in 616? Are there other interpretations this question does not consider?
