I would like do estimate the total number of different pictures I can represent by choosing a specific resolution and color depth, the number I'm getting seems somewhat low, so I'm wondering what am I doing wrong ?(adsbygoogle = window.adsbygoogle || []).push({});

Let the picture size be 45x45pixels with a color depth of 8 bits (2^8 = 256 different colors).

So 45x45=2025 total pixels. Each pixel can have 1 out of 256 colors assigned with repetition (for example, I can have a white image) and the order is important (for images which at least 1 pixel have a different assigned color) but reflected images could be discarded. I'm including an example to give size perception.

Therefore, the total number of combinations will be 2^8^2025 = 4.8521x10^{4876}

I was expecting a much larger number, one current processors could not calculate directly, any thoughts ?
