Attribution

The finite-field spike M_3^5 of Huh, Schroter, and Wang (Correlation bounds for fields and matroids, arXiv:1806.02675, Definition 19; discovered June 2018, no AI use reported in that record). Columns over GF(3): the tip e1, the vector e2+e3+e4+e5, and k*e1+e_m for m=2..5, k=1..p. Submitted from the literature.
