comment How do I express, algebraically, this comparison of two sets of sets?
I meant $|A1|+|A2|+|A3|$. But, yes, the sets are disjoint. Also, as there always be 3 subsets, I will probably choose to represent $J$ as $3$.

Thanks @goblin. I think I want $\sum_{j:J}|A_j|$ as the denominator. Is the ambiguity in my question related to the $+$ symbols in the denominators of the example?

@GA316 I mean the combined length of $A_1$, $A_2$ and $A_3$ (=6). I'm not sure of the correct representation at the moment.

comment How can I create a subset of the 'most dissimilar' combinations from a set of possible combinations?
@Fei Gao - Yes that seems to be a good match. Thanks.

Thanks, I am struggling to understand why it makes no sense at present. Any pointers much appreciated.
