Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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