Hi

**psolaki**,

I'll jump in as Ackbeet is offline, he can correct me later if I'm wrong

They are simply all the possible relationships for $\displaystyle \ \ a\not=b\not=c$

in relation to my o.p.

To put it another way (same result) just take all combinations of a b & c

abc

acb

bac

bca

cab

cba

and place a > between them. One of them

**must** be correct (as there is no other way they can be ordered), but in this particular case, it is impossible to find out which is correct with the given information.
