124 (one hundred [and] twenty-four) is the natural number following 123 and preceding 125.
In mathematics
[edit]
124 is an untouchable number, meaning that it is not the sum of proper divisors of any positive number.[1]
It is a stella octangula number, the number of spheres packed in the shape of a stellated octahedron.[2] It is also an icosahedral number.[3]
There are 124 different polygons of length 12 formed by edges of the integer lattice, counting two polygons as the same only when one is a translated copy of the other.[4]
124 is a perfectly partitioned number, meaning that it divides the number of partitions of 124. It is the first number to do so after 1, 2, and 3.[5]
In science
[edit]124 is the atomic number of unbiquadium, a hypothetical superactinide element.
