Presentation

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

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

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