Four of Diamonds: Building 38-3 Solution
Author: Adam Suhl Poem: Anand Sarwate
The picture depicts a floorplan of the Building 38 Athena cluster, with a
lettered box in the location of each computer. In the arithmetic
expressions, substitute the last digits of the computer's host name for the corresponding letter. (Each computer's hostname is
conveniently printed on a label stuck to the computer or seen on the
login screen.) Evaluating the arithmetic expressions yields values between 1 and 26; mapping them to letters gives the answer, GREAT DOME.
