(38G) First Programme for HP 38G: Integer Partitions (Using Gauss' Method) - Gerald H - 05-20-2014 06:01 PM
Edit: More easily readable & faster programme.
The programme's name is P4. Input a positive integer in the Home screen & actuate the programme. For input N = 6 the screen displays:
p(6)
11
Exact to N = 180
