Let R be a ring with identity and let M = M(1)circle plus...circle plus M-n
, be a finite direct sum of relatively projective R-modules M-i. Then it is
proved that M is lifting if and only if M is amply supplemented and M-i is
lifting for all 1 less than or equal to i less than or equal to n. Let M -
M(1)circle plus...circle plus M-n be a finite direct sum of R-modules Mi.
We prove that M is (quasi-) discrete if and only if M1, -, M, are relativel
y projective (quasi-) discrete modules. We also prove that, for an amply su
pplemented R-module M = M(1)circle plus M-2 such that M-1 and M-2 have the
finite exchange property, M is lifting if and only if n M-1 and M2 are lift
ing and relatively small projective R-modules and every co-closed submodule
N of M with M = N+M-1 = N + M-2 is a direct summand of M. Finally, we prov
e that, for a ring R such that every direct sum of a lifting R-module and a
simple R-module is lifting, every simple R-module is small M-projective fo
r any lifting R-module M.
