(m01 f04 v m05 f01) (m07 f02 v m06 f03) (m04 f08 v m03 f06) (m08 f07 v m02 f05)
(m05 f09 v m04 f10) (m06 f01 v m10 f03) (m09 f04 v m02 f06) (m03 f05 v m01 f02)
(m02 f03 v m01 f09) (m08 f10 v m03 f01) (m10 f08 v m07 f04) (m09 f07 v m04 f02)
(m07 f05 v m09 f01) (m08 f09 v m06 f06) (m05 f02 v m02 f08) (m01 f07 v m10 f10)
(m07 f09 v m03 f07) (m09 f10 v m06 f08) (m10 f06 v m05 f05) (m08 f03 v m04 f04)
It's not quite perfect, as the pair (f3 m6) meet twice).
