I t is easy by theory,but boring ,

There are 6 points,12 letters(or 8 letter.).So,It is boring at the detail,but it is simple in theory."而是很難,非常難,甚至可能是無解的".非常難OK,as 難no definition.無解is not OK.as it is theorem.There is no 無解的theorem in math.This Q at last is that verifying two polynomials are same.It is decidable.
