Using the CLEO II detector, we have measured the branching fractions for ϒ(3S)→ππϒ(1S), ϒ(3S)→ππϒ(2S), and the cascade ϒ(3S)→ϒ(2S)+X, ϒ(2S)→π+π-ϒ(1S), analyzing the exclusive mode where the daughter ϒ state decays to a e+e- or μ+μ- pair, as well as the inclusive π+π- transitions where the final ϒ state decays into hadrons. Properties of the ππ system are analyzed. Searches for the cascade decay ϒ(3S)→π+π-hb, hb→γηb and ϒ(3S)→π0hb were also performed.
