Exotic calcium lambda hypeuclei properties with the neutron number of 20-400 by a step of 20 are discussed by employing the relativistic continuum Hartree-Bogoliubov theory with a zero range pairing interaction. The Bethe-Weizs(a)cker mass formula of a multi-strange system and the Woods-Saxon-type potential of labda need to be modified for exotic calcium hypeuclei with unusual number of neutrons and lambdas. The possible neutron and lambda limits of exotic Ca labda hypeuclei are also investigated.
