Hadron locations on the rectangle
  Hadrons are located at the orthogonal intersections of 4-branes that wrap 1-cycles of a rectangular compact space. The 4-branes are arranged in a regular network. We reveal the conspicuous locations on the rectangle of the lightest mesons, unflavoured and of each flavour, of the lightest meson singlet states with hidden flavour of each kind, and of the lightest baryons of each flavour. The Higgs field vacuum expectation value is also associated with a conspicuous position on the rectangle, at the orthogonal intersection of 4-branes.
