  A potential model for four interacting quarks is constructed in SU(2) from
six basis states -- the three partitions into quark pairs, where the gluon
field is either in its ground state or first excited state. With four
independent parameters to describe the interactions connecting these basis
states, it is possible to fit 100 pieces of data -- the ground and first
excited states of configurations from six different four-quark geometries
calculated on a 16^3*32 lattice.
