In [6] we have constructed certain normal subgroups G7 of the elementary subgroup GR of the Chevalley group G(L, R) over R corresponding to a finite dimensional simple Lie algebra L over the complex field, where R is a commutative ring with identity. The method employed was to augment somewhat the generators of the elementary subgroup E I of G corresponding to an ideal I of the underlying Chevalley algebra LR;E I is thus the group generated by all xr(t) in G having the property that ter ⊂ I. In [6, § 5] we noted that in general E I actually had to be enlarged for a normal subgroup of GR to be obtained.
