A nice middle school scene with prime numbers. And also
a crazy algorithm for friendship. The coverage of prime numbers is nice. I like
the graph structure on the right. I wrote once
a paper: on primes, graphs and cohomology where such graphs appeared.
There is a tiny inaccuracy
on the white board, can you spot it? It is not as bad as in
Billy Madison, where the
prime numbers are covered too but where something more serious
was wrong. It is actually nice to have prime numbers covered in
middle school.
