Here's a problem I've recently discovered with Mathematica 3.0. In Mathematica 2.0: Mathematica 2.0 for NeXT Copyright 1988-91 Wolfram Research, Inc. -- NeXT graphics initialized -- In[1]:= EulerPhi[1] Out[1]= 1 In Mathematica 3.0: Mathematica 3.0 for Solaris Copyright 1988-96 Wolfram Research, Inc. -- Terminal graphics initialized -- In[1]:= EulerPhi[1] Out[1]= 0 My number theory text (Ireland and Rosen) defines it to EulerPhi[1] to be 1. This is consistent with the idea that EulerPhi[n] should be the number of primitive nth roots of unity. Cheers, -- knarF
