Abstract
It is shown that any sigma-complete Banach lattice, with an order semi -continuous norm containing an isomorphic copy of l(infinity), contain s an almost isometric copy of l(infinity). It is also proved that any Fenchel-Orlicz space (resp. the subspace of finite elements of any Fen chel-Orlicz space) generated by an Orlicz function not satisfying the suitable DELTA2-condition contains an almost isometric copy of l(infin ity) (resp. c0).
