Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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