Thank you, but it isn't the same.
I search this
CpQ = { { {a+x, b+y},{c+x,d+y},{ e+x , f+y} } , { {g + x ,h+y },{l+x ,m+y } } }
with tt ={x,y},
but your result code is
CpQ = { { {a+x, b+x},{c+x,d+x},{ e+x , f+x} } , { {g + y ,h+y },{l+y ,m+y } } }
We are near the correct form, but it isn't the final yet.
