Re: Synthesising every natural still life


Very strange to see that the asymmetric still life xs36_g88rbgzhaaaaahz1qq321 occurs in 3 different C1 soups, while its symmetric (cis?) variant xs36_g88rbgzhaaaaahz122rq1 has occured only once naturally (though there are plenty of symmetric soups from which it forms).
