The galaxy cluster MACS J0717.5+3745 (z=0.55) is the largest known cosmiclens, with complex internal structures seen in deep X-ray, Sunyaev-Zel'dovicheffect and dynamical observations. We perform a combined weak and stronglensing analysis with wide-field BVRi'z' Subaru/Suprime-Cam observations and16-band Hubble Space Telescope observations taken as part of the ClusterLensing And Supernova survey with Hubble (CLASH). We find consistent weakdistortion and magnification measurements of background galaxies, and combinethese signals to construct an optimally estimated radial mass profile of thecluster and its surrounding large-scale structure out to 5 Mpc/h. We findconsistency between strong-lensing and weak-lensing in the region where theseindependent data overlap, <500 kpc/h. The two-dimensional weak-lensing mapreveals a clear filamentary structure traced by distinct mass halos. We modelthe lensing shear field with 9 halos, including the main cluster, correspondingto mass peaks detected above 2.5\sigma_\kappa. The total mass of the cluster asdetermined by the different methods is M_{vir}=(2.8\pm0.4) \times 10^15 M_sun.Although this is the most massive cluster known at z>0.5, in terms of extremevalue statistics we conclude that the mass of MACS J0717.5+3745 by itself isnot in serious tension with LambdaCDM, representing only a ~2{\sigma} departureabove the maximum simulated halo mass at this redshift.
