s. griffin introduced a quotient $r_{n,\lambda}$ of the polynomial ring $\mathbb{q}$ with $\mathbb{q}$. it simultaneously generalizes the delta conjecture coinvariant rings of haglund-rhoades-shimozono and the cohomology rings of springer fibers studied by tanisaki and garsia-procesi. we describe the space $v_{n,\lambda}$ of harmonics attached to $r_{n,\lambda}$ and produce a harmonic basis of $r_{n,\lambda}$ indexed by certain ordered set partitions $\mathcal{op}_{n,\lambda}$. our description of $v_{n,\lambda}$ involves injective tableaux and vandermonde determinants. combinatorics of our harmonic basis is governed by a new extension of the lemher code. \\ \\ this is a joint work with brendon rhoades and zehong zhao.
