Hi,
following this simple demostrative process:
>> mod(42^8,4294967295)
ans =  1795713486
>> mod(429^8,4294967295)
ans =  1544028160
>> mod(4294^8,4294967295)
ans = 0
>> mod(42949^8,4294967295)
ans = 0
>> mod(429496^8,4294967295)
ans = 0
>> mod(4294967^8,4294967295)
ans = 0

one could simply see how that mod() function returns zero after its first
operand reaches some integer bias value.
