Presentation

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

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

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