  We extend earlier work on fully symmetric polynomials for three-boson wave
functions to arbitrarily many bosons and apply these to a light-front analysis
of the low-mass eigenstates of $\phi^4$ theory in 1+1 dimensions. The
basis-function approach allows the resolution in each Fock sector to be
independently optimized, which can be more efficient than the preset discrete
Fock states in DLCQ. We obtain an estimate of the critical coupling for
symmetry breaking in the positive mass-squared case.
