If a body is cremated, do the ashes transmit tumah as do other human remains, or does cremation render the body no longer tamei?
This is a matter of dispute in the Mishna Oholos 2:2. Rabbi Eliezer says one quarter kav worth of ash does transmit impurity, whilst the Sages say it does not transmit impurity at all. Rambam (Hilchos Tumas Meis 3:9-10) rules like the Sages.
