. . . . "analysis.py encodes each 16-bit mask as duplicated adjacent pairs on a periodic ring of width 32, applies rule 126 twice, and compares both cells of each pair with one step of rule 90. The same comparison is repeated for 40 double-steps on masks 256, 43690 and 42405." . . "Measured: 0 mismatches among 65536 pair-states (n = 65536, exact enumeration). Interpretation: The claim names rule 126 behaving like rule 90 when started from paired-cell blocks. The pair is the duplicated bit bb, and the match is every two steps, which is the alignment on which the two cells of a pair agree again. 'Quite common', and the further remark that class 3 rules can thereby act like class 2 rules, are outside this test." . "Claim test of wolfram2002-ch06-18: supports, confidence 0.93" . . .

"At least one pair-state of rule 126 whose image after two steps is not the pair-encoding of rule 90." . "A match shows only that this computation behaves as claimed. It says nothing about organisms." . "The encoding is duplicated bits, and the match is every two steps. A different block encoding is not ruled out or in." . "The stated example holds on this ring: 0 mismatches in 65536 pair-states, and 0 mismatched steps on the three trajectories (41 comparisons each, counting the initial state)." . "The test does not estimate how common such emulations are, and it does not check that class 3 rules can thereby act like class 2 rules. Those clauses of the claim are untested." . "Zero mismatches among the 65536 pair-states on the width-32 ring, and zero mismatched steps on the three 40-step trajectories." . "Pre-registered. Any pair-state whose two-step image is not the rule-90 encoding refutes the stated example. A trajectory mismatch with a clean exhaustive check is mixed. There is no other-pair survey to fail." .

"On a ring of 16 duplicated pairs, every two steps of rule 126 return both cells of each pair to the pair-encoding of one step of rule 90, for every one of the 65536 pair-states." . "Exhaustive comparison on the paired subspace, plus three locked orbits. A mismatch count of zero supports the stated example." . "Pre-registered. Encoding: each bit b is written as the adjacent pair bb. Ring width 32. For every mask in 0..65535, two steps of elementary rule 126 equal the pair-encoding of one step of elementary rule 90. The same equality is checked for 40 double-steps on three seeds: mask 256 (a single 1), mask 43690 (0xAAAA), and mask 42405 (0xA5A5). Supports if every pair-state matches and every trajectory step matches. This is only the stated pair rule 126 and rule 90. It is not a survey of other pairs, and it does not test the words 'quite common'." . "false"^^ . . "the stated pair, rule 126 emulating rule 90" . "generated data" . .
