Dear Nasser,
Thank you very much for your quick even when you are so busy.
The function HornerForm can factor part of the express, but still not the most compressed:
bb1 = Det[{{1, 1, 1}, {y2, y3, y4}, {z2, z3, z4}}]; bb = HornerForm[bb1]
The output is y4 z2 + y4 z3 + y3 (z2  z4) + y2 (z3 + z4)
appearently it can be factored furthermore: y4 (z3z2) + y3 (z2  z4) + y2 (z3 + z4)
Thanks, Tang Laoya
