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]
147 is the telephonic number of the 27 Brazilian Civil Police forces.
10 (ten) is the even natural number following 9 and preceding 11. Ten is the base of the decimal numeral system, the most common system of denoting numbers in both spoken and written language.
19 (nineteen) is the natural number following 18 and preceding 20. It is a prime number.
23 (twenty-three) is the natural number following 22 and preceding 24.
25 (twenty-five) is the natural number following 24 and preceding 26.
55 (fifty-five) is the natural number following 54 and preceding 56.
58 (fifty-eight) is the natural number following 57 and preceding 59.
63 (sixty-three) is the natural number following 62 and preceding 64.
1000 or one thousand is the natural number following 999 and preceding 1001. In most English-speaking countries, it can be written with or without a comma or sometimes a period separating the thousands digit: 1,000.
300 is the natural number following 299 and preceding 301.
144 is the natural number following 143 and preceding 145.

1,000,000, or one thousand thousand, is the natural number following 999,999 and preceding 1,000,001. The word is derived from the early Italian millione, from mille, "thousand", plus the augmentative suffix -one.
1,000,000,000 is the natural number following 999,999,999 and preceding 1,000,000,001. With a number, "billion" can be abbreviated as b, bil or bn.

276 is the natural number following 275 and preceding 277.
744 is the natural number following 743 and preceding 745.
The centered icosahedral numbers and cuboctahedral numbers are two different names for the same sequence of numbers, describing two different representations for these numbers as three-dimensional figurate numbers. As centered icosahedral numbers, they are centered numbers representing points arranged in the shape of a regular icosahedron. As cuboctahedral numbers, they represent points arranged in the shape of a cuboctahedron, and are a magic number for the face-centered cubic lattice. The centered icosahedral number for a specific is given by
