Is this it? Let F be a principle filter for XxY
and for all j in J, Gj a filter for YxZ. Then
. . F o /\_j Gj = /\{ F o Gj | j in J }.

Also if F filter for XxY, G,H filter for YxZ, then
. . F o G/\H = FoG /\ FoH.

Are there any additional distributive theorems for
reloids other than reversing the compositions?
