I think a 256 bit cipher has 2^256 combinations or 115792089237316195423570985008687907853269984665640564039457584007913129639936
I think a 320 bit cipher has this many combinations:
2135987035920910082395021706169552114602704522356652769947041607822219725780640550022962086936576

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
