I live in England. I am a native English speaker, and retain some schoolboy French. I have a science degree.

I can program in Prolog, Perl, and PHP, and write raw html.

I like maps.

I have an account on Wikimedia Commons.

Cayley Graphs[edit]

I have added one Cayley graph to an article. You can see it to the right, and at Pauli group. If you think it would be useful to have more such Cayley graphs of small groups in articles, please let me know, and I will provide them.

Thanks for edits[edit]

Maybe you have come here because I thanked you for an edit, and you are wondering what motivated me. (I have certainly wondered what has motivated some of the thanks that I have received.)

It might be because I saw your edit, and thought "that is a conspicuously good contribution to Wikipedia." Or it might be because your edit made me think "I wish I had said/done that." Or even both.

...for displaying civility during the energetically modified cement incident, based on my reading of previous entries on the article talk page. You conducted yourself there in a manner certainly worthy of admiration, given the persistent incivility I observed. Azx2 18:34, 31 March 2014 (UTC)

(This one, with its accompanying threat, was I think intended to deter me from reverting its donor's controversial edits to Tekhelet.)
