In mathematics[edit]

616 is the 25th member of the Padovan sequence, coming after 265, 351, 465 (it is the sum of the first two of these). 616 is a polygonal number in four different ways: it is a heptagonal number, as well as 13-, 31- and 104-gonal.

It is also the sum of the squares of the factorials of 2,3,4. i.e. (2!)^2 + (3!)^2 + (4!)^2 = 4+36+576=616.

The Roman numeral for 616, DCXVI, has exactly one occurrence of all symbols except for L whose value is less than 1000 (D=500, C=100, X=10, V=5, I=1).

The Number of the Beast[edit]

Main article: Number of the Beast

616 is believed by some to have been the original Number of the Beast in the Book of Revelation in the Christian Bible.[1] Different early versions of the Book of Revelation gave different numbers, and 666 had been widely accepted as the original number. In 2005, however, a fragment of papyrus 115 was revealed, containing the earliest known version of that part of the Book of Revelation discussing the Number of the Beast. It gave the number as 616, suggesting that this may have been the original.[2] Apparently the two different numbers reflect two different spellings of Emperor Nero/Neron's name, for which this number is believed to be a code.[3][4]
