The least additively principal ordinal is 1 since \(0 + 0 = 1\), and all additively principal ordinals other than 1 are limit ordinals. In particular, you can see from the Cantor normal form theorem (every ordinal has a CNF representation) that the additively principal ordinals are precisely the ord..." Tag: Visual edit
