I have a question: why are some two-suit combinations not present? (There's no Hist->Bonn card, or Trite->Shao, for example)
I realize now that I maybe have expressed myself badly, because English is not my first language.
By "not present" i don't mean the combination, i mean the order of symbols: A card with Hist and Bonn is present, but only in the "Bonn above, Hist below" combination. I was curious to ask why there was not a "Hist above, Bonn below" card as well.
