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