Widths 5-11, 3 variants, 9 corpora
Egypt corpus x columnar transposition sweep (widths 5-11, 3 variants, 9 corpora)
In plain English: Egypt corpus x columnar transposition sweep (widths 5-11, 3 variants, 9 corpora) — using a combined approach: scramble the letter order AND replace each letter.
This approach is ruled out within the tested scope.
NOISE
Tier 2
How to read this record
- Verdict – NOISE (no better than random guessing), INTERESTING (slightly above random, almost certainly coincidence), SIGNAL (statistically unusual, warrants investigation), or FULL MATCH (all 24 known letters correct).
- Confidence Tier – Tier 1 = mathematical proof (permanent). Tier 2 = every possibility tested. Tier 3 = partially tested. Tier 4 = not yet tested.
- Configs Tested – How many different key/parameter combinations were tried.
- Best Score – How many of the 24 known plaintext letters the best attempt matched (out of 24).
- Keystream Consistency (Bean) – Whether the key values at different positions are mathematically consistent with each other.
- Scope Limitations – What this elimination does not rule out.

Scope Limitations
This elimination does not rule out:
- Exhaustive for columnar widths 5-11 (44M permutations). Does not test width >= 12, non-columnar transpositions, or non-Egyptological source texts.
Assumptions
- Model A: CT[sigma(j)] = Enc(PT[j], Source[j+offset])
- Columnar transposition
- Running key from Egyptological corpus
- Vigenere/Beaufort/VB
