Mathematical optimization techniques are applied in order to find the most appropriate design for the superconducting bending magnets for the CERN Large Hadron Collider. By this means a coil block arrangement for a 56 mm aperture is derived, having a considerably reduced multipole content compared to that obtained in previous design studies. The Large Hadron Collider (LHC) project is proposed as the future extension of the CERN accelerator complex. The LHC requires twin aperture superconducting dipoles of highest possible field to guide the proton beams in the existing LEP tunnel of 26.7 km circumference and to make possible colliding experiments of up to 2 x 8 TeV [1]. Following a recent review suggesting an increased aperture and further reduction of the higher multipoles, especially of the 14 pole and 18 pole component, it became evident that a new coil geometry with new cable distribution had to be found. Mathematical optimization techniques have been applied in order to find a coil block arrangement with low multipole errors, high dipole field and a working point not higher than 95% along the load line.
