Presentation

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

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

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