    P1.P4 = (a)(s)(b c)(r w)(d v p j k x g z y o)(e i j m u n q l h t)
    P2.P5 = (a x t)(b l f q v e o u m)(c g y)(d)(h j p s w i z r n)(k)
    P3.P6 = (a b v i k t j g f c q n y)(d u z r e h l x w p s m o)

        1)  Guess most frequent (SYX SCW) as coming from 'aaa'.
        2)  Construct P3 and P6 as well as parts of P1, P2, P4, P5.
        3)  Look at AUQ AMN using P3 and P1 and then guess 'sss'.
        4)  Construct P2 and P5.
        5)  Look at RJL WPX (4) using P2 and P3 and then guess 'bbb'.
        6)  Look at LDR HDE (2) using P2 and P3 and then guess 'kkk'.
        7)  Consruct P1 and P4.

    P1 = (a s)(b r)(c w)(d i)(e v)(f h)(g n)(j o)(k l)(m y)(p t)(q x)(u z)
    P2 = (a y)(b j)(c t)(d k)(e i)(f h)(g x)(l n)(m p)(o w)(q r)(s u)(v z)
    P3 = (a x)(b l)(c m)(d g)(e i)(f o)(h v)(j u)(k r)(n p)(q s)(t z)(w y)
