+==============================================================================+

  CIPHER TYPE:     FHSS
  SECURITY LEVEL:  7/7

  STATUS:          [ACTIVE — AWAITING DECRYPTION]


  MISSION BRIEFING
  ----------------
6 characters transmitted over 32 channels (14 jammed). Each character sent 3 times. LCG seed 2426 governs the hop schedule.

  INTERCEPTED DATA
  ----------------





> hop frequencies:
  [11, 8, 1, 6, 7, 20, 29, 18, 3, 0, 25, 30, 31, 12, 21, 10, 27, 24]

  [{'hop': 0, 'freq': 11, 'char_idx': 0, 'char': 'Z', 'jammed': False}, {'hop': 1, 'freq': 8, 'char_idx': 1, 'char': 'L', 'jammed': False}, {'hop': 2, 'freq': 1, 'char_idx': 2, 'char': None, 'jammed': True}, {'hop': 3, 'freq': 6, 'char_idx': 3, 'char': 'U', 'jammed': False}, {'hop': 4, 'freq': 7, 'char_idx': 4, 'char': None, 'jammed': True}, {'hop': 5, 'freq': 20, 'char_idx': 5, 'char': None, 'jammed': True}, {'hop': 6, 'freq': 29, 'char_idx': 0, 'char': 'Z', 'jammed': False}, {'hop': 7, 'freq': 18, 'char_idx': 1, 'char': None, 'jammed': True}, {'hop': 8, 'freq': 3, 'char_idx': 2, 'char': None, 'jammed': True}, {'hop': 9, 'freq': 0, 'char_idx': 3, 'char': None, 'jammed': True}, {'hop': 10, 'freq': 25, 'char_idx': 4, 'char': 'F', 'jammed': False}, {'hop': 11, 'freq': 30, 'char_idx': 5, 'char': 'K', 'jammed': False}, {'hop': 12, 'freq': 31, 'char_idx': 0, 'char': 'Z', 'jammed': False}, {'hop': 13, 'freq': 12, 'char_idx': 1, 'char': None, 'jammed': True}, {'hop': 14, 'freq': 21, 'char_idx': 2, 'char': 'L', 'jammed': False}, {'hop': 15, 'freq': 10, 'char_idx': 3, 'char': None, 'jammed': True}, {'hop': 16, 'freq': 27, 'char_idx': 4, 'char': None, 'jammed': True}, {'hop': 17, 'freq': 24, 'char_idx': 5, 'char': None, 'jammed': True}]



> jammed channels:
  [0, 1, 3, 7, 10, 12, 13, 15, 18, 19, 20, 24, 27, 28]



> n channels:
  32



> n chars:
  6



> redundancy:
  3



> seed:
  2426



> lcg a:
  1103515245



> lcg c:
  12345



> lcg m:
  2147483648



> hint:
  LCG: x_i+1 = (a·x_i + c) mod m. Compute hop sequence from seed, find which hops survived jamming. Group surviving letters by char_idx to reconstruct the word.



> answer format:
  lowercase word, no spaces or punctuation
