What is your goal, taa? Supposing you are intelligent I prosume you could
imagine that I notice that you are anonymously spreading desinformation
and nonsense here. Because the castlings like in Chess960 are not
symmetric, there is no redundance of mirrored positions. And CRC of course
is not trying to get as few as possible starting arrays, but instead to
filter positions, which eventually could be used as polemic arguments
against CRC, and to secure a more harmonic impression of that approach.
