Bj's question: Pentaquark is created by $e^+e^-$. $2q + q \\to$ Baryon $; ~ ~ ~ 2q + \\bar q \\to $ Triquark$ ; ~ ~ ~ 2q + $Triquark $ \\to $Pentaquark Does it live long onough to be observable? Basic physics of constituent quarks and flavor antisymmetry. Report of $\\Theta^+$ violating flavor antisymmetry indicates need for two-cluster model.. Ball in Experimental Court - Some experiments see $\\Theta^+$; others don't. Possible production mechanisms present in some experiments, absent in others; e.g. via $N^*(2.3 \\rm{GeV}) \\to \\Theta^+ + \\bar K$?",
