Presentation

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

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

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