【 摘 要 】
An explicit formula for the Schur multiplier of the group of unitriangular matrices over products of cyclic rings Z/mZ and Z is derived. We use it to provide presentations of the corresponding covering groups and touch upon the question of finding their nonisomorphic representatives. (C) 2013 Elsevier Inc. All rights reserved.
