Albert and his two children were all born on exactly the same day. Albert is 20 years older than his first son Brian, who is 10 years older than his brother Charlie.
Their joint birthday is coming up soon, and two years ago the product of the ages of the two sons gave not only the exact date of their birthday that year, but also their 3 professions.
If their ages that year were A,B and C, then the cache is at:
N51 15.(B*C) W000 17.(A*13)+11
