The factorial is not scaled (example: &quot; fact stack{a#b} &quot; and &quot; fact {a over b} &quot; ) but is oriented using the baseline or centre of the arguments. Brackets always have a fixed size as well.
El carácter de factorial no se escala, (véase &quot; fact stack{a#b} &quot; y &quot; fact {a over b} &quot; ), sino que se alinea en la línea de base o en el centro del argumento.
