The pedal marks in bars 50 and 54 were added by Chopin in a proofreading of FE (→GE1). Lack of 
in bar 54 seems to be a result of an oversight, therefore, we add it under the 2nd quaver (the main text, after the pedalling of FE in bar 6) or under the 3rd quaver (an alternative suggestion, based on the pedalling of FE in bar 14 and adopted in bar 54 already in EE and subsequent GE,s).
