= Conformal quadrilateral
{title2=$(\Omega;a,b,c,d)$}

A <Jordan domain> together with four distinct boundary points in cyclic order, regarded up to a <conformal map> preserving those marked points. Such a domain maps to a rectangle with its marked points at the four corners. The opposite boundary-arc pairs specify two dual curve-joining problems whose <extremal lengths> are reciprocal.
