==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 <u>di</u>graphs of girth 4 over an extension ring of Z/4Z" [https://link.springer.com/article/10.1007/BF01787706] {{ZBL|0721.05028}} by Meiko Yamada, in that journal for <u>1990</u>, 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).  [[User:Richard Pinch|Richard Pinch]] ([[User talk:Richard Pinch|talk]]) 09:38, 26 March 2018 (CEST)
