f families "naturally in Ext(R.)", thus demonstrating that richness. On the other hand, there are families which belong to Ext(R.) in a more nonstandard way. Main results:.We conclude with a first look at Ext*(R.), which is the quotient semilattice of Ext(R.) modulo finite families. We prove that Ex
