In the main text we give the complementary fingering of GC (→GE1) and FE and EE, although it is possible that it was only the latter that was given by Chopin, as the copyist, having in front of him these four numerals, could have mistaken the figures and, after having correctly written the first two ones, could have added the last three four semiquavers further. In GE2, the third numeral was added in bar 45, whereas in GE3, the alleged return to the version of GE1 can be a result of the blurry imprint of this numeral.
