Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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