It is known that the joint distribution of the number of nodes of each type of an m-ary search tree is asymptotically multivariate normal when m ≤ 26. When m ≥ 27, we show the following strong asymptotics of the random vector Xn = t(Xn(1)),...,(Xn(m-1)), where Xn(i) denotes the number of nodes containing i - 1 keys after having introduced n - 1 keys in the tree: There exist (nonrandom) vectors X, C, and S and random variables ρ and φ such that (Xn - nX)/nσ2 - ρ(C cos(τ2log n + φ) + S sin(τ2log n + φ)) → n→∞0 almost surely and in L2; σ2 and τ2 denote the real and imaginary parts of one of the eigenvalues of the transition matrix, having the second greatest real part.
