P ~ 5 Group Of Order Since The Order Of The Automorphism Group (¦µ <sub> 1 </ Sub>-of ¦µ <sub> 5 </ Sub>),

Rodnoy james give a complete classification of all the groups of order p5 in [1],there are ten families from 1 to 10 .The calculation work of their order of automorphism comprises two parts, this paper produce the order of automorphism group of families from 1 to5 . Here p denotes an odd prime .
