## ExamUnimod contains 3 lists of matrices in GL(d,Z). Each of them
## generates a torsion-free abelian group with semisimple matrix algebra.
##
## Remark: These exemples were generated as normalsubgroupsgenerators
## of the kernel of the p-congruence homomorphism applied to
## MatExamples. The order is changes
## MatExamples(2) corresponds to ExamUnimod[1]
## MatExamples(3) corresponds to ExamUnimod[2]
## MatExamples(4) corresponds to ExamUnimod[3]
