Group

 * $G$

In this context, frequently seen in the compound symbol $\left({G, \circ}\right)$ where $\circ$ represents an arbitrary binary operation.

Function

 * $g \left({x}\right)$

The letter $g$, along with $f$ and $h$, is frequently used to denote a general mapping or function.

Geometric Distribution

 * $X \sim \operatorname{G}_0 \left({p}\right)$

$X$ has the geometric distribution with parameter $p$.

Shifted Geometric Distribution

 * $X \sim \operatorname{G}_1 \left({p}\right)$

$X$ has the shifted geometric distribution with parameter $p$.

Generating Function

 * $G_A \left({z}\right)$
