In FE, there are no accidentals on the 2nd and 3rd beats of the bar in the L.H. In the layout adopted by the majority of the editions, i.e. the first two semiquavers of the R.H. on the bottom stave, both sharps on the 3rd beat of the bar are to be considered necessary. The accidentals were added in GE1 (→GE2); moreover, a 
was added before c
1 at the end of the 2nd group of semiquavers. In EE, a was added before the last notes of the 2nd and 3rd groups. The layout of GE3 corresponds to the one adopted in our system; that edition contains all necessary sharps.
