[Tex/LaTex] ‘biggg’ in Latex/Lyx environment


I'm using Lyx editor and have added the amsmath environment. And in the editor, I can input the \biggg{ to show a slightly bigger { than the \bigg{. But it has errors when compiling the document. So, is there a bigger { than the \bigg{ or \Bigg{?

For example, in the following equation, I want the pair {} should be one level larger than the pair [] for better view. The {} for the equation is using \Bigg{ and \Bigg}.

and the original definition of \big & Co. is overwritten by amsmath, which replaces them by


Here \bBigg@ is the macro which actually does the scaling job: it takes an argument (the height in a length called \big@size). So you can use the following lines
