How to reduce a number of sets with OR operator in set analysis

[zhuravlevleonid]

Is there any posibilites not to copy all other conditions in set analysis?

I mean if i have conditions A, B, C, D, E or F

I should write them like {<A, B, C, D, E> + <A, B, C, D, F>}

And if i have two "OR " operators i should describe 4 sets:

A, B, C or D, E or F will look like:

{<A, B, C, E> + <A, B, C, F> + <A, B, D, E> + <A, B, D, F>}

And so on..

[tresesco · Accepted solution]

{<A, B, C, D, E> + <A, B, C, D, F>}  could perhaps be simplified as:

{<A, B, C, D>*( <E> + <F>)}

And the rest accordingly.

Thanks a lot!

Itl's exactly what i was looking for!

Worked well for me
