A geeky cache to celebrate the subject which I teach.
The cache is NOT at the above coordinates, but you could start your walk to the cache from here. The cache is at N A° B.C W D° E.F using the following clues:
A is the 16th prime number;
B is the 4th pentagonal pyramid number;
The prime factorisation of C is 2x3x7x13;
D is 50;
E is the fifth even nontotient number;
The factorial of F is the first factorial that is not a Harshad number.
