Available sources fail to provide the answer to the question whether the absence of a tie for f sharp in GC (→GE) was intended or accidental. Each of the versions seems fine from the musical point of view, also when we analyze that fragment in the context of its repetition 8 bars further on in the text: both the close analogy (f sharp in bar 81 and c sharp1 in bar 89 repeated) and the repetition with a slight modification (f sharp held in bar 81, c sharp1 repeated in bar 89) produce a natural effect.
