One of early the Heidi movies. An adaptation of a book of Johanna Spyri (1827-1901).
How many stars are there on a Swiss 1 Frank coin? There are some multiplication problems on the board.
Very interesting is the number table on the board to the right (I only was able to photograph
this while watching the movie on the plane. The scene below is from what one can find on the
internet). There is a very bad quality available
here on youtube. I need to get the DVD.
There is some information
here on SRF. Here is a reconstruction of this strange 9x9 matrix. It is not a multiplication table.
The last 4 columns appear to be permutations. A Suduku completion allows to see the 5th column.
Can somebody see what the pattern is?
Just put it on Twitter.
