Abstract
We present a general class of operators resembling compact tetraquarks which
have a range of colour-flavour-spin structures, transform irreducibly under the
symmetries of the lattice and respect other relevant symmetries. These
constructions are demonstrated in lattice QCD calculations with light quarks
