Do the two colors c and d have to be different? ("Let c be a color that is free on u and d be a color that is free on F[k].") &#32;                     (talk) 22:38, 8 June 2015 (UTC)

Colors c and d have to be different, otherwise we can't invert cd-path and can't make u d-free. 188.18.113.22 (talk) 20:04, 11 December 2017 (UTC)
