146 (one hundred [and] forty-six) is the natural number following 145 and preceding 147.
146 is an octahedral number, the number of spheres that can be packed into in a regular octahedron with six spheres along each edge. [1] For an octahedron with seven spheres along each edge, the number of spheres on the surface of the octahedron is again 146. [2] It is also possible to arrange 146 disks in the plane into an irregular octagon with six disks on each side, making 146 an octo number. [3]
There is no integer with exactly 146 coprimes less than it, so 146 is a nontotient. It is also never the difference between an integer and the total of coprimes below it, so it is a noncototient. [4] And it is not the sum of proper divisors of any number, making it an untouchable number. [5]
There are 146 connected partially ordered sets with four labeled elements. [6]
