Claim 14:
15. A combustor for a gas turbine engine having a centerline axis, comprising:
an annular inner liner;
an annular outer liner spaced apart from the inner liner;
a domed end disposed at an upstream end of the annular inner liner and the annular outer liner, the domed end including a ring of outer premixers with respect to the centerline axis and a ring of inner premixers with respect to the centerline axis, each of the outer premixers and each of the inner premixers having:
