I think a 256 bit cipher has 2^256 combinations or 115792089237316195423570985008687907853269984665640564039457584007913129639936

I think a 320 bit cipher has this many combinations:

I think the number of particals in the universe is 10^72 to 10^87 (http://www.stormloader.com/ajy/reallife.html). I think both numbers are smaller than 2^256
