Hear hear - Bladerunner.

Hi

OK, I get it. I thought:
To test Mx you do: 2^(2*(x-1))Mod Mx + 2^(2*(x-2)) Mod Mx +... 2^0 Mod Mx.

Was to be interpretatet as: (2^(2*(x-1))Mod (Mx + 2^(2*(x-2)))) Mod (Mx +... 2^0) Mod Mx....

Update:

This Python code should print the term after each Mod operation:

Mx = 5
term = 2**(2*(Mx-1))
for i in range(2,Mx+1):
print term
term = term % (Mx + 2**(2*(Mx-i)))
print term

2^2*(5-2) =...
