| a problem on 'shrinking polygons' | 28 Feb 2010 22:05 GMT | 1 |
Help would be appreciated with the following problem on 'shrinking polygons' - a generalisation of 'shrinking squares': let S be a sequence of n non-negative integers (a1, a2, a3, ..., a_n). Let the transformation T send S to (|a1-a2|, |a2-a3|, ..., |a_n-a1|).

Here is an unoriginal puzzle (stealing mostly from Soduku). The puzzle itself is easy to solve, but it was enjoyable for me to invent and to prove that there is only one solution. The 10 variables (m(0),m(1),m(2),...,m(9)) when their values are

We have been concerned NOT with this silly obsession about prime numbers/primality etc which has little bearing, as we are more concerned about the structure of Mathematics , Prime placement, and a new mathematics , in addition to correction of the .3333333333(11),
