What does "01" mean?

Hi,
I inspected the result and noticed that the '01' is actually a
LargePositiveInteger.
Then I used the 'normalize' message and got true for your expression
|r|
r := 501659.
(5 raisedTo: (r-1) modulo: r) normalize = 1
=>true
It would be nice that comparison primitives do automatically send
normalize message.
