Does anyone know if there is a feature in LibreOffice Math that enables the symbols to be rendered similar to the following tags used in LaTeX?:

[[math]] \bigcap_{n=1}^{10}A_{n} [[/math]]

and

[[math]] \bigcup_{n=1}^{10}A_{n} [[/math]]

Thank you!

Robert

p.s. The LaTeX code above should be on three separate lines ... they are merging in this description. Don't know how to avoid that text flow ... sorry. [[ and \ - backslash start new lines.

LaTeX rendered symbols down the page: ref

Try these in the formula editor:

stack {10 # size*3 {{} union {}} # n=1}A_n 
stack {10 # size*3 {{} intersection {}} # n=1}A_n

This choice was the best as it demonstrated the large intersection symbol albeit the upper and lower limit spans' text was a bit oversized and I couldn't find a method to adjust that. There probably is, I just don't know how to do it.

stack {size * .5 10 # size*3 {{} union {}} # size * .5 {n=1}}A_n

For union you can use a U as operator. Try this in the formula editor:

oper U from {n=1} to 10 A_n

If you find a symbol for intersection you can do the same (using oper).

I went with this method even though the intersection symbol [that I extracted from open symbol and pasted in the formula] was smaller ... even if I pasted a large character ... the limit texts were smaller and less invasive. It'd be nice if libreoffice could match LaTeX closer in appearance.
