Help with consensus terms in k-map solution

[asdf12312]

Homework Statement

Find consensus (redundant) terms for the minimal SOP solution for the following function (inputs A,B,C,D and output F):
Σm(1,3,4,5,7,10,11,12,14,15)

Homework Equations

n/a

The Attempt at a Solution

I find the minimal SOP solution is F=A'D + AC + BC'D'

Then it seems like there are three consensus terms which are CD + ABD' + A'BC'. But it seems like I am missing something else.
