Presentation

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

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

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