Tropical ideals are a class of ideals in the tropical polynomial semiring that combinatorially abstracts the possible collections of supports of all polynomials in an ideal over a field. We study zero-dimensional tropical idealsIwith Boolean coefficients in which all underlying matroids are paving matroids, or equivalently, in which all polynomials of minimal support have support of sizeor—we call them paving tropical ideals. We show that paving tropical ideals of degreeare in bijection with-invariantd-partitions of. This implies that zero-dimensional tropical ideals of degree 3 with Boolean coefficients are in bijection with-invariant 2-partitions of quotient groups of the form. We provide several applications of these techniques, including a construction of uncountably many zero-dimensional degree-3 tropical ideals in one variable with Boolean coefficients, and new examples of non-realizable zero-dimensional tropical ideals.
