Yes.  But "Сгсе.ru" is a whole-script confusable with "Crce.ru", and is

I think this standard was written by somebody with a PhD in Philosophy,
and not a programmer, so the language is very high falutin'.

So they're not actually suggesting that a list should be made, but the
result should be mathematically equivalent with the result of the
