147 (one hundred [and] forty-seven) is the natural number following 146 and preceding 148.
147 is the fourth centered icosahedral number. These are a class of figurate numbers that represent points in the shape of a regular icosahedron or alternatively points in the shape of a cuboctahedron, and are magic numbers for the face-centered cubic lattice. [1] Separately, it is also a magic number for the diamond cubic. [2]
It is also the fourth Apéry number following 19, where [3]
with 147 the composite index of the nineteenth triangle number, 190. [4] [5]
There are 147 different ways of representing one as a sum of unit fractions with five terms, allowing repeated fractions, [6] and 147 different self-avoiding polygonal chains of length six using horizontal and vertical segments of the integer lattice. [7]
147 is the highest possible break in snooker, in the absence of fouls and refereeing errors. [8]
In some traditions, there are 147 psalms. However, current Christian and Jewish traditions list a larger number, leading to the suggestion that some of the psalms in the earlier numbering were split into multiple pieces. [9] [10]
