Space group of heterogeneous cylinder packing with six 〈110〉 directions

Symmetrical structures of nonintersecting cylinders

“…Teshima et al [7] have reported three types of <110> cylinder packings with packing densities 0.494, 0.247 and 0.376. Teshima and Matsumoto [8] have studied the space group of last one. They have also proved that there is no <110> cylinder packing with cubic crystal symmetry.…”
