Presentation

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

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

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