let us rearrange the elements of S ( 4 , 3 ) as follows S ( 4 , 3 ) = { ( 1111 ) , ( 1112 ) , ( 1122 ) , ( 1222 ) , ( 2222 ) ⏟ ⏟ ( α α ) , ( 111 3 = ) , ( 112 3 = ) , ( 122 3 = ) , ( 222 3 = ) ⏟ ⏟ ( β β ) , ( 11 33 == ) , ( 12 33 == ) , ( 22 33 == ) ⏟ ⏟ ( γ γ ) , ( 1 333 === ) , ( 2 333 === ) ⏟ ⏟ ( δ δ ) ( 3333 ==== ) ⏟ ⏟ ( ω ω ) } .
