Local LCL properties [Levi, Mosheiff, and Shagrithaya (LMS), FOCS 2025] give a language to express a broad range of linear properties of codes. Subspace design [Guruswami and Xing, 2013] is an elegant property about the linear structure of codes, and it governs important code behavior. In this note, we show ... more >>>

We present a general framework for derandomizing random linear codes with respect to a broad class of permutation-invariant properties, known as local properties, which encompass several standard notions such as distance, list-decoding, list-recovery, and perfect hashing. Our approach extends the classical Alon-Edmonds-Luby (AEL) construction through a modified formalism of local ... more >>>
