N = 4 is the maximum number of independent supersymmetries: starting from a spin-1 field and using more supersymmetries, e.g., N = 5, only rotates between the 11 fields. To have N > 4 independent supersymmetries, one needs to start from a gauge field of spin higher than 1, e.g., a spin-2 tensor field such as that of the graviton.
Gmail is the email service provided by Google. As of 2019, it had 1.5 billion active users worldwide, making it the largest email service in the world.

The number e is a mathematical constant approximately equal to 2.71828 that can be characterized in many ways. It is the base of the natural logarithm function. It is the limit of as n tends to infinity, an expression that arises in the computation of compound interest. It is the value at 1 of the (natural) exponential function, commonly ...
The unitary group is a subgroup of the general linear group GL (n, C), and it has as a subgroup the special unitary group, consisting of those unitary matrices with determinant 1. In the simple case n = 1, the group U (1) corresponds to the circle group, consisting of all complex numbers with absolute value 1, under multiplication.
Infobox references. (E,E)-2,4-Decadienal is an aromatic substance found in butter, cooked beef, fish, potato chips, roasted peanut, [2] buckwheat [3] and wheat bread crumb. [4] In an isolated state, it smells of deep fat flavor, characteristic of chicken aroma (at 10 ppm ). At lower concentration, it has the odor of citrus, orange or grapefruit.
2 ( two) is a number, numeral and digit. It is the natural number following 1 and preceding 3. It is the smallest and only even prime number. Because it forms the basis of a duality, it has religious and spiritual significance in many cultures .
Data Universal Numbering System. The Data Universal Numbering System, abbreviated as DUNS or D-U-N-S, is a proprietary system developed and managed by Dun & Bradstreet (D&B) that assigns a unique numeric identifier, referred to as a "DUNS number" to a single business entity. It was introduced in 1963 to support D&B's credit reporting practice.
