FOUR

4 is the smallest squared prime (p2) and the only even number in this form. It has an aliquot sum of 3 which is itself prime. The aliquot sequence of 4 has 4 members (4, 3, 1, 0) and is accordingly the first member of the 3-aliquot tree.

A number is a multiple of 4 if its last two digits are a multiple of 4. For example, 1092 is a multiple of 4 because 92 = 4×23.

Only one number has an aliquot sum of 4 and that is squared prime 9.

A four-sided plane figure is a quadrilateral (quadrangle) or square, sometimes also called a tetragon. A circle divided by 4 makes right angles. Because of it, four (4) is the base number of plane (mathematics). Four cardinal directions, four seasons, duodecimal system, and vigesimal system are based on four.

A solid figure with four faces is a tetrahedron. The regular tetrahedron is the simplest Platonic solid. A tetrahedron, which can also be called a 3-simplex, has four triangular faces and four vertices. It is the only self-dual regular polyhedron.

Four-dimensional space is the highest-dimensional space featuring more than three convex regular figures.

In Buddhism the four Noble Truths are:
Dukkha – The Noble Truth of Suffering
Samudaya – The Noble Truth of the Cause of Suffering
Nirodha – The Noble Truth of the Cessation of Suffering
Magga – The Noble Truth of the Path leading to the Cessation of Suffering

The Chinese, Vietnamese, the Korean and the Japanese are superstitious about the number four because it is a homonym for "Death" in their languages.

Channel 4 is a British public-service television broadcaster which began transmission on 2 November 1982. Although largely commercially self-funded, it is ultimately publicly-owned; originally a subsidiary of the Independent Broadcasting Authority (IBA), the station is now owned and operated by Channel Four Television Corporation, a public body established in 1990, coming into operation in 1993. With the conversion of the Wenvoe transmitter in Wales to digital on 31 March 2010, Channel 4 became an entirely UK-wide TV channel for the first time.

The channel was established to provide a fourth television service to the United Kingdom in addition to the television licence–funded BBC's two services and the single commercial broadcasting network, ITV.
