The body of the tables contain the characters in the respective irreducible representations for each respective symmetry operation, or set of symmetry operations. The symbol i used in the body of the table denotes the imaginary unit: i 2 = −1. Used in a column heading, it denotes the operation of inversion.
The irreducible complex characters of a finite group form a character table which encodes much useful information about the group G in a concise form. Each row is labelled by an irreducible character and the entries in the row are the values of that character on any representative of the respective conjugacy class of G (because characters are class functions).
English: Character tables of binary tetrahedral, octahedral and icosahedral subgroups from "Ueber die Composition der Charaktere einer Gruppe", Sitzungsberichte der Königlich Preussischen Akademie der Wissenschaften zu Berlin, Deutsche Akademie der Wissenschaften zu Berlin, 6 April 1899, page 339
The space of complex-valued class functions of a finite group G has a natural inner product: , := | | () ¯ where () ¯ denotes the complex conjugate of the value of on g.With respect to this inner product, the irreducible characters form an orthonormal basis for the space of class functions, and this yields the orthogonality relation for the rows of the character table:

The ethynyl radical (systematically named λ 3-ethyne and hydridodicarbon(C—C)) is an organic compound with the chemical formula C≡CH (also written [CCH] or C 2 H).It is a simple molecule that does not occur naturally on Earth but is abundant in the interstellar medium.
[[Category:Character set table templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Character set table templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last character.
The Unicode Consortium and the ISO/IEC JTC 1/SC 2/WG 2 jointly collaborate on the list of the characters in the Universal Coded Character Set.The Universal Coded Character Set, most commonly called the Universal Character Set (abbr. UCS, official designation: ISO/IEC 10646), is an international standard to map characters, discrete symbols used in natural language, mathematics, music, and other ...
