In A (→FC→GE) the topmost notes of the L.H. part (d
1 and higher) are written on the top stave, while in b. 19 the R.H. g notes are placed on the bottom stave:
(the accidentals and the order of the overlapping quavers in the right and left hands are presented according to A; in FC the 
before E was omitted, and GE supplemented accidentals and introduced some changes in the horizontal arrangement of chords). In FE (→EE) this seemingly illegible notation was simplified by placing the part of each of the hands on a separate stave, which we also adopted to the main text. According to us, the complexity of the original notation resulted in the double Terzverschreibung mistake in b. 21 in GE.
