In my article on a presentation of the Rubik's cube group last night,
I omitted a relator from list ((7)):

    v es v cs v es^-1 v cs^-1.

This brings the number of relators to 44, with a total length of 605.
Experiments with GAP on some smaller cube-like groups indicate that
with this addition, the presentation is correct.

My apologies for the error.
