b. 7

composition: Op. 28 No. 3, Prelude in G major

No arpeggio sign in FCI & A (→FE,FCGE)

Arpeggio sign in EE

..

Arpeggio in EE resulted from a mistake of the engraver of EE1, who placed it in b. 7 instead of b. 8.

b. 18

composition: Op. 28 No. 3, Prelude in G major

No arpeggio sign in FCI

Arpeggio sign in A (→FCGE, →FEEE)

..

FCI does not contain any of the arpeggios present in the remaining sources (cf. b. 24 and 32-33); therefore, Chopin most probably added them only just in the last stage of editing the Prelude.

No arpeggio sign in FCI

Arpeggio for 3 notes in A (→FC,FEEE

2-note arpeggio in GE

..

The shorter arpeggio wavy line in GE is a mistake, although it is difficult to say whether it is a mere inaccuracy or a misunderstanding in the interpretation of the notation of FC.
The missing arpeggio sign in FCI – see b. 18 and 32-33.

b. 32-33

composition: Op. 28 No. 3, Prelude in G major

No arpeggio signs in FCI

Arpeggio signs in A (→FCGE, →FEEE)

..

The missing arpeggios in FCI could be explained by inaccuracy, caused by, e.g. lack of space in FCI or in the lost autograph on which it was based. However, taking into account the fact that FCI does not contain any of the arpeggios present in the final version (cf. b. 18 and 24), it is most probably an earlier version.
