## Binary Operation

- $\intercal$

Used in 1975: T.S. Blyth: *Set Theory and Abstract Algebra* to denote an arbitrary binary operation in a general algebraic structure.

It is given the name **truc**, pronounced **trook**, French for **trick** or **technique**.

Blyth himself suggests that **truc** could be translated as **thingummyjig**, but this is linguistically unsupported, and is probably idiosyncratic.

The $\LaTeX$ code for \(\intercal\) is `\intercal`
