Presentation

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

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

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