An illustration of computing the frequency vector \(\pmb {w}=\pmb {f}(T\langle +1\rangle ) \in \text {W}_{\text {main}}^{(\delta _1+1)}({\mathtt{a}}, d, m)\) of a tri-rooted tree T from the frequency vectors \(\pmb {w}^1=\pmb {f}(T_1[+2])\in \text {W}_{\text {end}+2}^{(\delta _1+1)}({\mathtt{a}}, d-1, m'')\) and \(\pmb {w}^2=\pmb {f}(T_2[+1])\in \text {W}_{\text {end}}^{(\delta _2)}({\mathtt{a}}', d', m')\) for bi-rooted trees \(T_1\) and \(T_2\)
