I'm just looking for the correct term to describe a concept:

Suppose I have a 5x5 matrix:

 A B C D E F G H I J K L M N O P Q R S T U V W X Y 

I can pick any two cells, let's say the cells I and Q, and observe that if I follow the row and column until they "collide," I get two more cells that form the corners of a submatrix. In other words, cells G and S are significant because they are on the same row/column of I and Q.

My question is this: Is there a term for the relationship between G and S in this situation? Anitpodes? Contras? Sisters?

    G and S are the first and last entries in the main diagonal of the submatrix determined by I and Q.2012-04-03

    I don't see anything better than "corners"... on that note, your description as written is fine; no need for anything fancier, really.2012-04-03

    You're lucky you didn't run out of letters there.2012-04-04

    @Bruno There's a reason the example is 5x5 :)2012-04-04
