Re^6: Very Large Hex Combinations

There are a whole lot more than 640*480*2^24 true colour images. There are 307200 pixels (640*480), each of which can take 2^24 different colours. That leads to 2^(24*640*480) different images, that is 2^7372800. That's a number that takes more than 2 million digits to write down.

Arg! You're right! That's how I did it originally, but I thought I had it wrong. There are `2^(24640480)` true colour 640x480 images. That's a number with over 2211840 digits. Considering a googol has only 101 digits and "a googol is much larger than the number of atoms in the Universe", your goal is unfeasable. Even if we used 128x128x16 thumbnails, it's still unfeasable at 2^(4128128), a number with over 19660 digits. There is over a googol of 20x20 monochrome images. (Over 2.58 * 10^120, to be more precise.)	[reply] [d/l]

As I said in another post, even 8x8 bitmaps are unfeasable. 2^64 is a very large number. A 6x6 bitmap needs four and a half byte of storage, storing all of them requires 288 Tb. That's feasable.	[reply]
