Presentation

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

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

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