U+22CA Right Normal Factor Semidirect Product

U+22CA was added to Unicode in version 1.1 (1993). It belongs to the block U+2200 to U+22FF Mathematical Operators in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Math Symbol and is commonly used, that is, in no specific script.

The glyph is not a composition. It has a Neutral East Asian Width. In bidirectional context it acts as Other Neutral and is mirrored. Its corresponding mirrored glyph is Glyph for U+22C9 Left Normal Factor Semidirect Product. In text U+22CA behaves as Alphabetic regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

The Wikipedia has the following information about this codepoint:

A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various types, many symbols are needed for expressing all mathematics.

The most basic symbols are the decimal digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9), and the letters of the Latin alphabet. The decimal digits are used for representing numbers through the Hindu–Arabic numeral system. Historically, upper-case letters were used for representing points in geometry, and lower-case letters were used for variables and constants. Letters are used for representing many other sorts of mathematical objects. As the number of these sorts has remarkably increased in modern mathematics, the Greek alphabet and some Hebrew letters are also used. In mathematical formulas, the standard typeface is italic type for Latin letters and lower-case Greek letters, and upright type for upper case Greek letters. For having more symbols, other typefaces are also used, mainly boldface a , A , b , B , … {displaystyle mathbf {a,A,b,B} ,ldots } , script typeface A , B , … {displaystyle {mathcal {A,B}},ldots } (the lower-case script face is rarely used because of the possible confusion with the standard face), German fraktur a , A , b , B , … {displaystyle {mathfrak {a,A,b,B}},ldots } , and blackboard bold N , Z , Q , R , C , H , F q {displaystyle mathbb {N,Z,Q,R,C,H,F} _{q}} (the other letters are rarely used in this face, or their use is unconventional).

The use of Latin and Greek letters as symbols for denoting mathematical objects is not described in this article. For such uses, see Variable (mathematics) and List of mathematical constants. However, some symbols that are described here have the same shape as the letter from which they are derived, such as ∏ {displaystyle extstyle prod {}} and ∑ {displaystyle extstyle sum {}} .

These letters alone are not sufficient for the needs of mathematicians, and many other symbols are used. Some take their origin in punctuation marks and diacritics traditionally used in typography; others by deforming letter forms, as in the cases of ∈ {displaystyle in } and ∀ {displaystyle forall } . Others, such as + and =, were specially designed for mathematics.
