This is too good not to report!
I looked at my Google Scholar page today. One of the items had an asterisk by it, so I decided to explore. It helpfully explained that this citation may include more than one item. On exploring further, I discovered that as well as
Designs, graphs, codes, and their links
PJ Cameron, JH Van Lint – 1992
Cited by 385
there was also
Codes, and their Links
PJ Cameron, JH Van Lint, G Designs – 1991
Cited by 92
But they don’t list “G Designs” among my co-authors. Should this researcher have Erdős number 2?? And why the different year?
