It seems like the expression you provided is a bit unclear due to formatting issues. It looks like you're trying to define a matrix or a system of numbers, but the formatting is not showing correctly.

Could you please clarify or provide a more specific format for your equation or expression? For example, is this a matrix you're trying to define? If so, could you restate the elements or structure more clearly?

Feel free to rephrase or upload a photo of the problem!
