Hi,

autonumber stores the expression value and gives it a unique integer value whereas autonumberhash128 stores just the hash value (in 128 bits) of the corresponding expression value. similarly autonumberhash256 stores the value (in 256 bits) of the corresponding expression value.

Hope it will helpful!!

Autonumber() stores the expression value in its lookup table whereas autonumberhash128() stores just the 128bit hash value of the expression value. I'm sure you can guess therefore, autonumberhash256() stores the 256bit hash value expression value
