AI has a g
1 as the 11th semiquaver, otherwise written with a superfluous 
. Chopin had to then change it into a g
1, which is featured in FE (→EE). The fact of not considering this change in GE – unless it is a common mistake of the engraver – may reveal that it was not introduced until the last proofreading of FE. In GE4 (→GE5) the was deleted, unnecessary in the version with g1 (together with the equally superfluous before a1 on the penultimate semiquaver).
