Presentation

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

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

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