PUZZLE #4953: LWE Cipher (diff 1)

lwe learn difficulty: 1/7 reason author: system unsolved

Recover the secret vector s from the LWE instance A·s + e = b (mod 97). 6 equations, 3 unknowns, noise bound ±0.

DATA
A [85, 81, 18], [11, 37, 49], [28, 10, 80], [64, 2, 18], [89, 77, 68], [66, 87, 17]
B 28, 46, 55, 81, 30, 70
Q 97
N 3
M 6
Error Scale 0
Hint Recover the secret vector s of length 3 from A·s + e = b (mod 97). System is 6 equations, 3 unknowns. Zero noise — solve exactly via Gaussian elimination. Convert s entries (0-25) to letters a-z for the answer.
Answer Format short lowercase string matching the secret vector length
