Deletion of Tadao Takaoka

Comment: He works in graph theory and combinatorics; the publication rate there is fairly fast and an h-index of 12 is not really impressive, especially for someone with a pretty long career. No individual cites in triple digits, so I don't think any of his papers qualifies as very highly cited. Nothing else in the record seems particularly substantive in terms of satisfying . The only thing that gives me some pause is that most of his work was probably done before 1990 and our electronic search tools may not be very good in dealing with old references. Still in the absence of more explicit evidence of notability, I don't think that this passes

Comment: per Nsk92. Guest editorship of a special issue of a journal is not enough for  #8
