    then best to have a list including also the less exotic examples. Have now started one here.

    Also adjusted your line to include pointer to (0,1)-category, in order to bring out the pattern.

    And I adjusted the (old) paragraph now right before this list of examples, for generality and hyperlinking.

    Can we guess what makes a (1,2)(1,2)-topos differ from an ordinary topos from the case of Pos? It contains an object which does what ⊥→⊤\bottom \to \top does in Pos, i.e., classifying something?

    Classifying sieves = monic fibrations.
