[Solved] Intersection Symbol with Nothing in Front of it

Can someone please tell me how to create this - the whole statement, exactly as shown - in the formula writer?

Translated literally: "the intersection of all indexed elements on set A divided by set B"

Thank you, in advance.

Use a dummy operand, empty set of braces:
Code: Select all   Expand viewCollapse view
{} intersection _{i in l} (A_i setminus B)

As far as I can see many publications prefer to put the quantifying operands larger than the binary operands and often also bold. I do not know a rule concerning the factor, but 150% should be a good estimate.
Code: Select all   Expand viewCollapse view
{{boldĀ {size*1.5 {{}intersection{}}}} sub{i in I} (A sub i setminus B)}
will do as decribed.
I do not know a way to apply a From { } To { } style (like with the Sum quantifyer) to intersection.
