Sigh... You seem to want to prove things by example... As you know examples disprove things but do not prove them. What I mean is, you focused on the first occurrence of random and missed the second where the "highly" is missing... Is "unique" subjective as well?

I am really sorry, but I have started to find this discussion boring. I have studied probability and randomness for 20 years, use it for at least 10 years in a very applied context, so if you want, I am happy to buy you a beer and have a nice discussion about it in the right context. An internet forum is not it, and I am sure everyone here wishes this thread goes away.

You're a scientist of some kind, yes? I assume you've published a paper of decent quality. If that is indeed the case you know that using a word like "highly" is subjective, unless some norm or normative relation is provided/established.

And now you've come to the internet to defend a specious argument. Fap, fap, fap.

This is the second link in the google "x-trans random" search:

The X-E1's sensor adopts the same high-performance 16M X-Trans CMOS found in the X Series flagship X-Pro1 model. Featuring an originally developed color filter array with a highly RANDOM pixel arrangement, its X-Trans CMOS sensor eliminates the need for an optical low-pass filter, which is used in conventional systems to inhibit moiré at the expense of resolution. The innovative array lets the X-Trans CMOS sensor capture unfiltered light from the lens and produce unprecedented resolution. The unique RANDOM arrangement of the color filter array is also highly effective in enhancing noise separation in high-sensitivity photography.

"Moiré is tackled at its root cause by the innovative color filter array of the new sensor. By enhancing the aperiodicity (randomness) in the array arrangement, the color filter minimizes the generation of moire and false colors, eliminating the necessity for an optical low-pass filter in the lens and enabling the sensor to capture the full “unfiltered” resolution and descriptive quality of the XF lens."

So they do not say it's a random distribution.

They say their design enhances the aperiodicity (randomness).

Just so we're sticking to the facts, and not ranting on about the wrong thing...
