b. 20
Omission of the a1 note seems to be a result of Chopin's proofreading, who could have removed it to avoid false relation with the A-a octave on the 4th beat of the bar (in analogous bar 88, in which a remained in the chord, the ending chord is different). However, the version of A (→GE) may be certainly considered an equal variant.
