Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(2,4)(5,6)(7,8)(9,10)(11,12)(15,23)(16,17)(19,27)(20,21)(24,28)(25,26);(1,2)(3,4)(13,14,18,22)(15,24,26,27)(16,21,17,20)(19,23,28,25);(6,8)(13,15,18,26)(14,19,22,28)(16,25,17,23)(20,24,21,27);(2,4)(10,12)
