%N Largest GF2X-Matula number i which encodes a tree of n nodes, i.e., for which A091238(i) = n.

%C Apparently from n=4 onward given by recurrence a(4) = A014580(4), a(5) = A014580(A014580(4)), a(6) = A014580(A014580(A014580(4))), etc.

%Y Analogous to A005518. A091239 gives the smallest i with number of nodes = n. Cf. A091230, A091238, A091241.
