Our method to obtain the $m$th moment of the density of transmission eigenvalues requires two correlated sets of $m$ classical trajectories, therefore generalizing previous works on conductance and shot noise. The semiclassical results agree, for all values of $m$, with the corresponding predictions from random matrix theory.12 pages, 6 figures; v2-added some references; v3-Substantial changes in presentation (results remain the same): we have removed all reference to quantum graphs, and now treat generic chaotic cavities; v4-Largely expanded, now has 5 sections and an appendixMesoscale and Nanoscale PhysicsChaotic Dynamicstext
