MathDB

(Mathematicians A to Z) Below are the names of 26 mathematicians, one for each letter of the alphabet. Your answer to this question should be a subset of

\{A,B,\cdots,Z\}

, where each letter represents the corresponding mathematician. If two mathematicians in your subset have birthdates that are within

20

years of each other, then your score is

0

. Otherwise, your score is

\max(3(k-3),0)

where

k

is the number of elements in your set.
