184 (one hundred [and] eighty-four) is the natural number following 183 and preceding 185.

In mathematics

[edit]

There are 184 different Eulerian graphs on eight unlabeled vertices,[1] and 184 paths by which a chess rook can travel from one corner of a 4 × 4 chessboard to the opposite corner without passing through the same square twice.[2] 184 is also a refactorable number.

In other fields

[edit]

Some physicists have proposed that 184 is a magic number for neutrons in atomic nuclei.[3][4]

In poker, with one or more jokers as wild cards, there are 184 different straight flushes.[5]
