Sorry if this question is naive, I have just started using Sage. I was playing around with Carmichael numbers and wanted to produce a list of a^n mod n for various values of a.
I thought the code for k in range(2,5): j = k.powermod(n,n)
would do what I wanted. But I get the error message 'int' object has no attribute 'powermod'
Any suggestions?
The problem is that range produces Python int, not Sage integers, hence the powermod method is not avaiable. Just replace range with srange and it shoud work !
Using pow(a, b, c) instead of a.powermod(b, c) should work.
