The problem is you can't conclude
Then isn't another quantifier elimination all you need (i.e. prove that Cube(e) and Dodec(d) implies FrontOf(d, e)) ?
Also I'm wondering if you mixed up the order of e and y in step 4.
FrontOf(d, e)
from step 4, isn't it?Then isn't another quantifier elimination all you need (i.e. prove that Cube(e) and Dodec(d) implies FrontOf(d, e)) ?
