Abstract Exotic calcium lambda hypernuclei 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--Weizsäcker mass formula of a multi-strange system and the Woods--Saxon-type potential of lambda need to be modified for exotic calcium hypernuclei with unusual number of neutrons and lambdas. The possible neutron and lambda limits of exotic Ca lambda hypernuclei are also investigated.
