Talk:Galois ring

Problem with reference

Reference a10 – M. Yamada, "Distance regular graphs of girth 4 over an extension ring of $\mathbf{Z}/4$" Graphs and Combinatorics , 6 (1980) pp. 381–384 – does not exist. Indeed, the journal in question did not begin publication until 1985. I suggest that the reference should probably be to the similarly titled article, "Distance-regular digraphs of girth 4 over an extension ring of Z/4Z" [1] Zbl 0721.05028 by Meiko Yamada, in that journal for 1990, volume and pages as described.

There is also a minor problem with a4 -- "An upper bound for Weil-type exponential sums over Galois rings and applications" -- presumably this is DOI 10.1109/18.370147 Zbl 0853.11098 in which case the title is "An upper bound for Weil exponential sums over Galois rings and applications" in IEEE Trans. Inf. Theory 41, No.2, 456-468 (1995). Richard Pinch (talk) 09:38, 26 March 2018 (CEST)
