Abstract
The isometries of homogeneous Gödel-type Riemannian spacetimes are reexamined. An extension of the Raychaudhuri-Thakurta-Rebouças-Tiomno analysis is made. It is shown that the m=2Ω case admits a seven-parameter group of motions. Comments on the unique Gödel-type causal model are made. The isometries for the degenerate Gödel-type metrics (Ω=0) are also obtained.Keywords
