This article introduces a new edition of P.Rain. Unterricht kopt. 311, a piece of paper containing an Arabic account recently described by Petra Sijpesteijn (on one side) and a multiplication table (the first six columns on side B and the last column on side A at right angles of the document). New reflections on the Arabic text, as well as new readings and interpretations of the Greek table, shed light on the background of the document and its writing.
