Addendum to “Set-theoretic complete intersection monomial curves in affine four space” [J. Algebra 372 (2012) 463–479]

We prove that every monomial curve C in affine four space, defined by natural numbers n1, n2, n3 and n4, is a set-theoretic complete intersection, if one of n1, n2, n3, n4 is less than or equal to 14.
