Abstract
In the paper [1] mentioned in the title, the authors attempted to determine the Schur multipliers of the five simple Mathieu groups. In rechecking the calculations, we find that an error was made, leading to incorrect results for M12 and M22. Our purpose here is to compute again the multipliers of M12 and M22, which turn out to be cyclic groups of orders 2 and 6 respectively. The multipliers of M11M23, M24 were originally (and correctly) determined to be trivial.Keywords
