[#R274] Classify sequences with totally unimodular sum matrices
1Summary
Determine which increasing integer sequences make every finite sum-indicator matrix totally unimodular.
Positive examples include several recurrence and exponential sequences. The determinant-2 recurrence example rules out a growth-only answer.
Conjectured evidence. Replay readiness: source only.
