%N Continued fraction that converts to its own decimal expansion; the sequence becomes strictly increasing when all zero terms are removed.

%C Because this continued fraction converts to its own decimal expansion (x = 0.3295478438074556404146870856456305081000402384373...), it is called a base-10 Trott number by Allaart.
