Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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