'automata' is the plural form

Jul 21, 2012 at 17:56 comment added Erik I think it should be a+b*(c|ca+b*)*
Jul 21, 2012 at 15:19 comment added Niel de Beaudrap It turns out that it's only slightly incorrect: can you see how? -- I knew a prof who had written a very nice textbook on Abstract Algebra (Keith Nicholson) in its 3rd edition: he seemed to have had lots of problems with trivial errors in the exercises, and was glad to get the feedback.

Jul 21, 2012 at 14:10 comment added Niel de Beaudrap It's pretty clear that the two are a mismatch, for the reason you give. Is there a reason why you doubt yourself?
