In bar 56 the earlier start of the slur in FE (→GE,EE; overlooked in EE2) seems to be an inaccuracy of the engraver, in spite of the fact that it is compatible with – according to us, apparently – lack of tie of f1. In turn, lack of the slur in bar 57 in FE (→GE1→GE1a→GE2→GE3) is almost certainly a mistake.
