Another point of interest in the position (reproduced below for convenience) is that it contains a 5-cell XY ring in r4c367, r6c37 (marked with "*" below). XY rings sometimes yield a large number of eliminations. For any side of an XY ring, the common value shared by the two vertex cells can be eliminated from any cell which sees both vertices. In this case, three of the sides produce one or more eliminations. The eliminations are marked with the "-" symbol placed before the eliminated digit.
