what about the solution on 16th floor? Transpose procedure might work (but not sure). In practice, 100K*100K table is useless in any way. unable to calcuate, unable to print, unable to query...
But any way, I think the matrix is additive by row of same names(?), plus to mirror the elements by diagonal from right to left corner...
