This is a letter-substitution code puzzle: each letter maps to a fixed digit, and the mapping is derived from the example word MOBILITY (M=4, O=6, B=2, I=9, L=3, T=2, Y=7). Applying that same per-letter mapping consistently to EXAMINATION (including repeated letters like I, N, A, T lining up correctly) produces the digit string 56149512965, confirming internal consistency of the code.
