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 .
