Extract

In 1951 received a letter from Prof. H. Davenport, F.R.S., with some information about the factors of 12n ± 1. The results he gave were interesting and not obvious; whether they were novel I do not know. It occurs to me (whether strictly novel or not) they might well be worth publishing, as of general interest and as a tribute to a great and kindly man. However, since Prof. Davenport’s letter was not intended for publication as written, I paraphrase it here with explanation of the background.
