  We present unpublished work of D.Carter, G.Keller, and E.Paige on bounded
generation in special linear groups. Let n be a positive integer, and let A = O
be the ring of integers of an algebraic number field K (or, more generally, let
A be a localization O_S.) If n = 2, assume that A has infinitely many units.
  We show there is a finite-index subgroup H of SL(n,A), such that every matrix
in H is a product of a bounded number of elementary matrices. We also show that
if T is in SL(n,A), and T is not a scalar matrix, then there is a finite-index,
normal subgroup N of SL(n,A), such that every element of N is a product of a
bounded number of conjugates of T.
  For n > 2, these results remain valid when SL(n,A) is replaced by any of its
subgroups of finite index.
