The missing wedge for the L.H. octave is a mistake of FESB (revision? – in this layout the wedge could have seemed superfluous, since the one over the R.H. chord is valid for the L.H. too). A comparison with b. 46 reveals that in this version of the initial motif of the theme of the Variations, Chopin wanted to mark each of the first three notes with staccato markings (different – see the next note).
