DUN 238 AB + KO 5AC + TOK 434Ba,Bb: HIP 110712 and 110719 form the 20".6
pair DUN 238 AB. We observed both components. The A component has a
variable RV according to the GCS, but not confirmed by Jones et al.
(2002); it was unresolved. The newly found pair Ba,Bb has a period on CPS2002b
the order of 10yr. Considering the distant companion Cab2012
C found by Caballero (2012), the system contains at least 4 stars. Tok2015c
