(When this problem was first published on the
site, we made a mistake. We've now
corrected it but would still like to thank all those of you who
wrote to point out our error. Children at Much Wenlock Primary
School, Hotwells Primary School, Downsview School, King Henry VIII
Abergavenny, Brocks Hill Primary School, Eastwood Comprehensive,
Rebecca at Gateway Primary School and Benjamin at Holmead Middle
School all explained that in fact it was impossible to solve.)
