To solve this expression, we will follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

First, let's simplify the expressions inside the parentheses:

8 - 1 = 7

(-1,6) - 4 = -1 - 4 = -5

Next, let's square 4:

4^2 = 16

Now, let's put it all together:

(-2:16):7,6:-5,5

Now, let's perform the division:

-2 ÷ 16 = -0.125

That leaves us with:

-0.125:7,6:-5,5

Now, let's evaluate the remaining expressions:

-0.125:7 ≈ -0.017857143

6:-5 = 1.2

Now, putting it all together:

-0.017857143, 1.2, 5
