Sorry, I think I was not enough clear nor explicit.

I want to  to show the 2-simplex (in R^2) obtained from the inequality

x+ y+ z < = 12

x, y, z  >= 0.

(the angles of the triangle are (12,0,0), (0,12,0) and (0,0,12) )

The CORE of a cooperative game, is the set points that additionally satisfy the system

x+ y >= 6

x+ z >= 6

y + z >= 6

(In this case, it will be a triangle with angles (6,6,0), (0,6,6) and (6,0,6) ).

How can I obtain --and visualize the core -- with Maple?

Indeed, I would like to obtain something like the graphic attached in the file CORE_mapleprimes.pdf

Thanks a lot for your patience,
