This puzzle refers to the periodic table mural in the lobby of Building 6 (across from the plaque of George Eastman, whose nose students often touch for luck). When the sequence
VII 2; V 4; IV 2; VII 1; VII 6; II 3; IV 3; VI 1; V 1
is clued into the periodic table by columns and rows, it produces the answer:
Cl As Si F I Ca Ti O N
