Is there any article that help me study automorphisms of nilpotent groups of class two with cyclic center? In "ODD ORDER NILPOTENT GROUPS OF CLASS TWO WITH CYCLIC CENTRE"Odd order nilpotent groups of class two with cyclic centre,Y Y. K. LEONG Leong (1974)" there is a presentation of nilpotent groups of class two with cyclic center. How can I find the structure of automorphisms of these groups by using this presentations?
