Question 1208263
<pre>
It has to be like this:

{{{drawing(100,100,-1.5,1.5,-1.5,1.5,
locate(cos(pi/2-2pi/14),sin(pi/2-2pi/14),MS),
locate(cos(pi/2+2pi/14),sin(pi/2+2pi/14),MS),
locate(cos(pi/2+2pi/14+2pi/7),sin(pi/2+2pi/14+2pi/7),FT),
locate(cos(pi/2+2pi/14+2*2pi/7),sin(pi/2+2pi/14+2*2pi/7),FS),
locate(cos(pi/2+2pi/14+3*2pi/7),sin(pi/2+2pi/14+3*2pi/7),FT),
locate(cos(pi/2+2pi/14+4*2pi/7),sin(pi/2+2pi/14+4*2pi/7),FS),
locate(cos(pi/2+2pi/14+5*2pi/7),sin(pi/2+2pi/14+5*2pi/7),FT) )}}}

2! ways to seat the MS's, the male students.
3! ways to seat the FT's, the female teachers.
2! ways to seat the FS's, the female students.

(2!)(3!)(2!) =(2)(6)(2) = 24 ways.
