Authored summary

The attractive total-domination route stops at 4-connectivity because the exact invariant is 12. The cited theorem would require gamma_t greater than 14 to certify 6-connectivity.

The record reports a computation within its stated scope. The outcome applies to this attempt's recorded scope.

The outcome reports what was recorded. Its scope and evidence grade remain separate. Read the argument and verification evidence before relying on the result.

2Authored explanation

The action was to compute \(\gamma_t\) exactly and feed it into the total-domination connectivity theorem. The search examined every candidate size allowed by the elementary lower bound until it found the optimum 12.

To obtain 6-connectivity from Theorem 2.3, set \(k=7\). Its strict hypothesis becomes \(\gamma_t(G)>14\). The exact value 12 violates that hypothesis. The same theorem certifies 4-connectivity and cannot certify 5-connectivity, whose hypothesis would be \(\gamma_t(G)>12\).

This failure boundary is exact. Improving the total-domination search or finding a different minimum witness cannot extend this theorem's result for the same graph. Another topological argument is required.
